The highly functional chromio nitrile ylides Cr(CO)5C=N-C(Cl)- PR3 (R = Ph, NMe2) (2a, b) form readily in mixtures of Cr(CO)5CNCCl3 (1) with the respective phosphanes. Their reactions without isolation with the acylating agent Cr(CO)5CN(C=O)Ar (Ar = C6H4-P-NO2), MeO2CC? CCO2Me, ketones (R2C=O, R = Me, Et; 2R = 9-fluorenediyl) and phenyl isocyanate to give the Cl/COAr-substitution- (6a), alkyne insertion- (10) and [3+2] cycloaddition products (13, 14) are described. Formation of the latter is accompanied by an interligand CC coupling with loss of P(NMe 2)3 and OP(NMe2)3 (after hydrolysis). Their reactions are compared with, those of the parent compounds LnMCN-C(H)-PPh3.

High filling fraction gallium phosphide (GaP) inverse opals were fabricated by atomic layer deposition within the void spaces of silica colloidal crystal templates. Depositions were performed from 400 to 500 C using trimethylgallium and tris(dimethylamino)phosphine precursors. The resulting films were characterized by optical reflectance, which indicated infiltration as high as 100% of the conformal film growth maximum, corresponding to a volume filling fraction of 0.224. X-ray diffraction measurements confirmed the crystallinity of the film. These results indicate the fabrication of three-dimensional photonic crystals using a III-V optoelectronic material with sufficient dielectric contrast to form a full photonic band gap in the visible.

Diumycinol <2(Z),6(E)-12-(2-methylene-6,6-dimethyl-1-cyclohexyl)-11-methylene-3,8,8-trimethyldodeca-2,6-dien-1-ol>, a hydrolytic product of the antibiotic diumycin, was assembled from three fragments: 1-(2-phenylsulphonylethyl)-2-methylene-6,6-dimethylcyclohexane (28), 3-(2-iodoethyl)-3-methyloxetane (39), and (Z)-1-benzyloxy-6-phenylsulphonyl-3-methylhex-2-ene (3).An efficient synthesis of 2-methylene-6,6-dimethylcyclohexylmethanol (15) (gamma-cyclogeraniol) was accomplished by a <2,3>sigmatropic rearrangement of 3,3-dimethylcyclohex-1-enylmethoxymethyl-lithium (17).

Eleven chiral trivalent or quatrivalent phosphorus reagents were synthesized starting from L-proline, D-camphor, (+)- or (-)-1,1′-binaphthalene-2,2′-diol, (-)-alpha-phenylethylamine, etc. and their application as catalysts in asymmetric borane reduction of N-phenyl imine of acetophenone was preliminary investigated. N-Phenyl alpha-phenylethylamine was obtained in good yield with low to moderate enantioselectivity.

The structural isomerism in R3PSe(Ph)I compounds and the ionic structure of [(Me2N)3PSePh]I were discussed. The ionic compound [(Me2N)3PSePh]I was found to contain a long Se-I contact, 3.825 A, and a bent P-Se-I angle, 114.5 A. The analysis showed discrepancy in the N-P-N angles, two being similar, 105.1 A and 107.0 A with the third was significantly greater.

A racemic 1,1?-spirobitetralin-8,8?-diol (SBITOL) was conveniently synthesized from 3-methoxybenzaldehyde in 26 % yield over 9 steps and resolved via its bis-(S)-camphorsulfonates. The corresponding chiral spirobitetraline monophosphoramidite ligands have been prepared and their rhodium complexes were applied in the asymmetric hydrogenation of dehydroamino esters with good to excellent enantioselectivities (up to 99.3% ee).

Natural abundance 13C NMR studies have been carried out on a series of organophosphorus compounds possessing P-N bonds.For the first time a one-bond temperature-dependent 13C-31P nuclear spin coupling was observed for the P-phenyl carbons in bis(N,N-dibenzylamino)phenylphosphine (0-9 Hz) and bis(N,N-diethylamino)phenylphosphine (0-2 Hz).This temperature-dependent behavior can be rationalized in terms of free rotation about the phenyl phosphorus bond with concomitant hindered rotation about the P-N bonds.A conformational preference for the nitrogen and phosphorus lone pairs to exist in the trans orientation is indicated.In the similarly substituted 5-membered heterocyclic ring compound, 1,3-dimethyl-2-phenyl-1,3-diazaphospholidine, the phenyl one-bond coupling increases to (-) 42.1 Hz and becomes temperature independent.These data suggest that 1J(PC) is very responsive to electronic effects.

Phosphorylation and cyclophosphorylation of 1,4-dihydroxyanthracene and dianthrone by hexaalkylphosphorous triamides in pyridine was effected for the first time. The phosphorylation rate is found depending on the type of the alkyl fragment in the amido group of the phosphorylating agent. Cyclic phosphoramidites derived from anthracene were prepared both by molecular assembling and direct cyclophosphorylation. Thio and oxo derivatives of these cyclic compounds were obtained. Dianthrone derivatives undergo intramolecular cycloaddition at only one anthracene fragment to form an interesting bulky structure containing the phospholane ring.

Iron Thiocarbonyl Complex, Carbon Carbon Coupling, Desulfurization, Iron Sulfur Bond Slow addition of Fe(CO)4CS (1) to an excess of P(NMe2)3 (2) in pentane produces S=P(NMe2)3 (3) and a tar-like material from which small amounts of violet crystals of (CO)2<*>FeS=CC(O)=S<*> (4) could be isolated. 4 crystallizes in the space group P21/c, Z = 4, a = 13.124(1), b = 14.131(2), c = 14.070(1) Angstroem; beta = 91.71(1) deg.The iron atom is trigonal-bipyramidally coordinated and bears a chelating ligand formed by C-C coupling between the former CS group and one CO group of 1 and an additional S atom, incorporated probably via the sulfide 3.One P(NMe2)3 unit coordinates at the iron atom and the other one at the former thiocarbonyl carbon atom.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: P[N(CH3)2]3, you can also check out more blogs about1608-26-0

A method is proposed for one-pot synthesis of either symmetrical or unsimmetrical diester amidophosphites, developed on the basis of tris-(N,N-dimethyl)-amideof phosphorous acid, activated by iodine, as a new phosphorylating reagent.Nine thiophosphate, phosphite and phosphite monoester and diester derivatives of 1-O-steraoylethane-2-ol, cholesterol, beta-sitosterol and R,S-alpha-tocopherol have been synthesized under mild conditions (20-75 deg C) and in high final yields (83-98percent).
