Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 1608-26-0, Name is Tris(dimethylamino)phosphine
, COA of Formula: P[N(CH3)2]3.

The compounds Ph3PSeI2, (Me2N)3PSeI2 and (Et2N)3PSeI2 have been prepared and characterised by 31P-{H} NMR and infrared spectroscopy. Their single crystal structures have also been determined. Interesting variations in d(P-Se) and d(I-I) are noted upon changing R (Ph, Me2N, Et2N). The variation in d(P-Se) for R3PSeI2 compared to the parent tertiary phosphine selenide is also discussed with respect to the degree of retention of phosphorus selenium double-bond character upon co-ordination of I2. The variations in d(P-Se) and d(I-I) are reflected in the infrared and 31P-{H} NMR spectra of the R3PSeI2 compounds when compared to R3PSe (R = Ph, Me2N or Et2N). The P-Se-I geometries for all three compounds are bent [Ph3PSeI2, 106.0(1), (Me2N)3PSeI2, 100.4(2) (average); (Et2N)3PSeI2, 106.4(1)] whereas the Se-I-I linkages are all essentially linear [173.69(6), 174.98(8) (average); 178.04(5)]. These results are interpreted as a donation of electron density from the selenium atom to the sigma*-antibonding orbital of the diiodine.

The application of homogeneously soluble catalysts is limited by the recovery in cases where the price of the catalyst is high. Biological catalysts, enzymes, can be efficiently recycled by means of an ultrafiltration membrane due to their high molecular weight, for example, in the continuously operated membrane reactor. In order to transfer this principle to chemical catalysis, we have attached a transfer hydrogenation catalyst, first invented by Gao and Noyori, to a polymer. The resulting homogeneously soluble, polymer-bound catalyst (chemzyme) can now be retained by ultrafiltration membranes like enzymes. On applying this catalyst in continuously operated membrane reactors, a continuous isopropoxide dosage is necessary in order to compensate deactivation caused by water residues in the feed stream. Thus, high space-time yields up to 578 g L-1 d-1 and enantioselectivities up to 94% can he achieved. These results were compared to an enzyme catalyzed system consisting of a carbonyl reductase that also utilizes 2-propanol as a hydrogen source for the cofactor regeneration of NADH.

Monomeric thiosalicylaldiminate complexes of rhodium(I) and iridium(I) were prepared by ligand transfer from the homoleptic zinc(II) species. In the presence of strongly donating ligands, the iridium complexes undergo insertion of the metal into the imine carbon-hydrogen bond. Thiophenoxyketimines were prepared by nontemplated reaction of o-mercaptoacetophenone with anilines and were complexed with rhodium(I), iridium(I), nickel(II), and platinum(II). X-ray crystallographic studies showed that while the thiosalicylaldiminate complexes display planar ligand conformations, those of the thiophenoxyketiminates are strongly distorted. Results of a computational study predicted that all synthetically accessible thiophenoxyketiminates will display distorted geometries.

A novel tetranuclear Ag(i) complex, [Ag4(mu-DMPTP)2(POP)3][BF4]2 (Ag4N2P3), has been designed to achieve highly efficient thermally activated delayed fluorescence (TADF). Photophysical investigations show that the compound exhibits highly efficient TADF (Phi = 76%) and has a very short ambient-temperature TADF decay time of only 0.65 mus, corresponding to a radiative decay rate of k = Phi/tau = 1.2 × 106 s-1, a value belonging to the fast radiative rates in TADF materials.

As part of our efforts to identify a suitable back-up compound to our recently disclosed mGlu5 positive allosteric modulator (PAM) clinical candidate VU0490551/JNJ-46778212, this letter details the investigation and challenges of a novel series of 6,7-dihydropyrazolo[1,5-a]pyrazin-4-one derivatives. From these efforts, compound 4k emerged as a potent and selective mGlu5 PAM displaying overall attractive in vitro (pharmacological and ADMET) and PK profiles combined with in vivo efficacy in preclinical models of schizophrenia. However, further advancement of the compound was precluded due to severely limiting CNS-related side-effects confirming the previously reported association between excessive mGlu5 activation and target-related toxicities.

A document type is Article, introducing its new discovery., Formula: C39H32OP2

A series of gold(I) iodide complexes 1?11 have been prepared from di-, tri-, and tetraphosphane ligands. Crystallographic studies reveal that the di- (1?7) and tetrametallic (11) compounds feature linearly coordinated gold(I) ions with short aurophilic contacts. Their luminescence behavior is determined by the combined influence of the phosphane properties, metal?metal interaction, and intermolecular lattice-defined interactions. The proposed variable contribution of 3(X+M)-centered (X=halogen; M=metal) and 3XLCT (halogen to ligand charge transfer) electronic transitions into the lowest lying excited state, which is influenced by supramolecular packing, is presumably responsible for the alteration of room-temperature emission color from green (lambda=545 nm, for 11) to near-IR (lambda=698 nm, for 2). Dinuclear compounds 6 and 7 exhibit distinct luminescence thermochromism with a blueshift up to 5750 cm?1 upon cooling. Such dramatic change of emission energy is assigned to the presence of two coupled triplet excited states of 3pipi* and 3(X+M)C/3XLCT nature, the presence of which depends on both molecular structure and the crystal lattice arrangement.
