Convenient synthetic method of functional phosphines under photochemical conditions

Steady-state photolysis of triarylphosphines, Ar3P, under an argon atmosphere in a solvent with the structure CH3X (X = CN, COOC2H5, COCH3) afforded an adduct with the solvent molecule, Ar2PCH2X, in significant amount. This photoreaction is acknowledged as a convenient method to prepare functional phosphines.

Synthesis, reactivity and solid-state structural studies of new phosphino copper(I) derivatives of hydrotris(3-methyl-2-thioxo-1-imidazolyl)borate

1:1:1 [(R3P)Cu(Tm)] (R = phenyl, cyclohexyl, m- and p-tolyl) or [(R?Ph2P)Cu(Tm)] (R? = methyl or ethyl) triorganophosphine copper(I) adducts, containing the anionic, potential S3-, face-capping ligand hydrotris(3-methyl-1-imidazolyl-2-thione)borate [Tm]-, were synthesised from K[Tm], CuCl and the corresponding P-donor. No phosphine adduct was obtained when tri-o-tolyl-, tribenzyl-phosphine, triphenylarsine and triphenylantimony were reacted with K[Tm] and CuCl, [Cu(Tm)]n being the product obtained always, in strong excess of the phosphorus donor. The probably polynuclear [Cu(Tm)]n is stable towards Hmimt (3-methyl-1-imidazoline-2-thione), NH3, CS2, H2O and CO; it reacts with pyridine (py) to yield the 1:1:1 adduct [(py)Cu(Tm)]. [Cu(Tm)]n also reacts with H2O2 yielding the poorly soluble derivative [Cu(mimt)]n upon breaking of the B-N bond in the azolyl-borate ligand. All of the complexes synthesised were characterised through analytical and spectral (IR, 1H and 31P NMR) measurements. The solid-state structures of [(m-tolyl3P)Cu(Tm)] and [(p-tolyl3P)Cu(Tm)] show the copper atoms to be tetracoordinate with the donor [Tm] behaving as an S3-, face-capping ligand.

The diamond-shaped heterometallic cyanide-bridged complex of iron(II) and copper(I), [CpFe(CO)(mu-CN)2Cu(CH3CN)2]2 (1), has been synthesized from the reaction of K[CpFe(CO)(CN)2] and [Cu(CH3CN)4][BF4] in acetonitrile. Upon the addition of 2-4 equivalents of phosphane ligands to complex 1, the coordination geometry of the copper centers can be varied from trigonal planar as in [CpFe(CO)(mu-CN)2Cu(PCy3)]2 (2), to tetrahedral as found in [CpFe(CO)(mu-CN)2Cu(PCy3)2]2 (3). Analogous derivatives containing other phosphane ligands, namely PMe3, P(p-tolyl)3, PMe2Ph, and PPh2Me have been synthesized as well. Prolonged exposure of complex 3 in CH2Cl2 to excess PCy3 has provided the bimetallic complex [CpFe(PCy3)(CN)(mu-CN) Cu(PCy3)2] (4), where the metal aggregate is disrupted and PCy3 has displaced CO at the iron center. Bidentate phosphane analogs of complex 3 have been prepared by adding two equivalents of dcpe [bis(dicyclohexylphosphanyl)-ethane] or dcpp [bis(dicyclohexylphosphanyl)propane] to complex 1. The solid-state structures of several of these diamond-shaped derivatives, in addition to complex 4, have been determined by X-ray crystallography. The overlapping diamond-shaped [Fe2(CN)4Cu2] cores, which form channels within the solids, are blocked by bulky, copper-bound phosphane ligands such as PCy3. However, in the case of the small phosphane PMe3, or the chelating phosphanes dcpe and dcpp, these channels are not blocked by the phosphane ligands; solvent molecules occupy the channels created by the overlapping metal cores instead. Alternatively, the complex [CpFe(CO)(CN)(mu-CN)Cu(dcpm)]2 (13), derived from bis(dicyclohexylphosphanyl)methane(dcpm), possesses two copper(I) centers, each in a distorted trigonal coordination geometry, bridged by two dcpm ligands to form an eight-membered metallacycle with a short CuI···CuI separation of 2.844 A. The third ligand completing each copper’s coordination sphere is a nitrogen-bound bridging cyanide group from a CpFe(CO)(CN)2- anion.

Palladium-catalyzed Pd-aryl/P-aryl interchange reaction was applied in the synthesis of various functionalized arylphosphines. This phosphination used inexpensive, readily available and air stable triarylphosphines as the phosphinating agents. Broad functional groups were compatible including keto, aldehyde, ester, nitrile, ether, chloride, pyridyl and thiophenyl groups. Halides were found to be good promoter for the rates and yields of the reaction.

Application of 213697-53-1. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 213697-53-1, Name is 2′-(Dicyclohexylphosphino)-N,N-dimethyl-[1,1′-biphenyl]-2-amine. In a document type is Article, introducing its new discovery.

We report herein a visible-light-promoted, highly practical carboxylation of readily accessible aryl triflates at ambient temperature and a balloon pressure of CO2 by the combined use of palladium and photoredox Ir(III) catalysts. Strikingly, the stoichiometric metallic reductant is replaced by a nonmetallic amine reductant providing an environmentally benign carboxylation process. In addition, one-pot synthesis of a carboxylic acid directly from phenol and modification of estrone and concise synthesis of pharmaceutical drugs adapalene and bexarotene have been accomplished via late-stage carboxylation reaction. Furthermore, a parallel decarboxylation-carboxylation reaction has been demonstrated in an H-type closed vessel that is an interesting concept for the strategic sector. Spectroscopic and spectroelectrochemical studies indicated electron transfer from the Ir(III)/DIPEA combination to generate aryl carboxylate and Pd(0) for catalytic turnover.

A direct and practical metal-free N-H phosphorylation has been achieved via the TBHP/NH4I-mediated cross-dehydrogenative coupling (CDC) reactions between imines/imidates and P(O)H compounds. This transformation provides an efficient synthetic route to the construction of P-N bonds with good functional group compatibility, leading to the formation of N-phosphorylimines and N-phosphorylimidates in up to 95% yield (33 examples) under mild conditions.
