Photocatalytic Arylation of P4 and PH3: Reaction Development Through Mechanistic Insight

Detailed 31P{1H} NMR spectroscopic investigations provide deeper insight into the complex, multi-step mechanisms involved in the recently reported photocatalytic arylation of white phosphorus (P4). Specifically, these studies have identified a number of previously unrecognized side products, which arise from an unexpected non-innocent behavior of the commonly employed terminal reductant Et3N. The different rate of formation of these products explains discrepancies in the performance of the two most effective catalysts, [Ir(dtbbpy)(ppy)2][PF6] (dtbbpy=4,4′-di-tert-butyl-2,2′-bipyridine) and 3DPAFIPN. Inspired by the observation of PH3 as a minor intermediate, we have developed the first catalytic procedure for the arylation of this key industrial compound. Similar to P4 arylation, this method affords valuable triarylphosphines or tetraarylphosphonium salts depending on the steric profile of the aryl substituents.

Multinuclear Cu(I) Clusters Featuring a New Triply Bridging Coordination Mode of Phosphaamidinate Ligands

Phosphabenzamidine [mes-NH-C(Ph)=P-mes) (1) and phosphaformamidine (mes-NH-CH=P-mes) (4) ligands have been synthesized and characterized. The conjugate bases of 1 and 4 coordinate by each bridging three Cu(I) ions, forming hexa- and tetranuclear clusters Cu6[mes-N=C(Ph)-P-mes]3Cl4Li(THF)2 (3) and Cu4[mes-N=CH-P-mes]4 (5), respectively. Both clusters have been fully characterized using 1H NMR, 31P NMR, and X-ray crystallography. Complexes 3 and 5 exhibit a previously unknown coordination mode of phosphaamidinates, which are far less studied than their well-known amidinate counterparts.

Phosphino[tris(trimethylsilyl)methyl]boranes and 2,4- bis[tris(trimethylsilyl)methyl]-1,3,2,4-diphosphadiboretanes [1]

The reaction of tris(trimethylsilyl)methylboron dihalides (Me 3Si)3CBX2 (X = Cl, F) with the lithium phosphides LiPHtBu and LiPHmes leads to the phosphinoboranes (Me 3Si)3CBX-(PHR), (Me3Si)3CB(PHR) 2 or the 1,3,2,4-diphosphadiboretanes [(Me3Si) 3CB(PR)]2, depending on the ratio of the reagents, the reaction temperature and concentration. High dilution and low temperatures are required for the synthesis of (Me3Si)3CB(Hal)PHR (1-3) in order to prevent the formation of (Me3Si)3CB(PHR) 2 (4 and 5). The latter compounds are best prepared in a two step phosphination from (Me3Si)3CBHal2 and LiPHR. At higher temperatures the four-membered 1,3,2,4-diphosphadiboretanes [(Me 3Si)3CB(PR)]2 6 and 7 are the most stable compounds. On the other hand, compounds of type (Me3Si) 3CB(Hal)PR2, 8 and 9, are thermally more stable than the monophosphinoboranes 1-3. Phosphinoboranes of type (Me3Si) 3CB(PR2)2 (R = tBu, mes) could not be prepared. NMR and mass spectral data are in accord with the monomeric nature of compounds 1 to 9.
