Reduction of tertiary phosphine oxides to phosphine-boranes using Ti(Oi-Pr)4/BH3-THF

A new method for reduction of tertiary phosphine oxides leading to the formation of tertiary phosphine-boranes has been developed. The BH3-THF/Ti(Oi-Pr)4 reducing system enables conversion of triaryl, diarylalkyl and trialkylphosphine oxides directly to their borane analogues in good to high yields. In contrast to the previously reported protocols, the presence of activating groups in the structure of starting material is not necessary for the reaction to occur. The reaction is highly stereoselective and proceeds with predominant retention of configuration at the phosphorus atom. A plausible mechanism of reduction of the P[dbnd]O bond by BH3-THF/Ti(Oi-Pr)4 has been proposed.

Heterolytic H2 cleavage and catalytic hydrogenation by an iron metallaboratrane

Reversible, heterolytic addition of H2 across an iron-boron bond in a ferraboratrane with formal hydride transfer to the boron gives iron-borohydrido-hydride complexes. These compounds catalyze the hydrogenation of alkenes and alkynes to the respective alkanes. Notably, the boron is capable of acting as a shuttle for hydride transfer to substrates. The results are interesting in the context of heterolytic substrate addition across metal-boron bonds in metallaboratranes and related systems, as well as metal-ligand bifunctional catalysis.

OPTISCH AKTIVE PHOSPHINE DURCH ASYMMETRISCHE SUBSTITUTION PROCHIRALER, HOMOCHIRAL SUBSTITUIERTER PHOSPHONITE

Phenylphosphonous acid dimenthylester and its dibornylester react with bulky nucleophiles to give diastereomeric phosphinous acid esters.The asymmetric induction is as high as 95 percent d.e.If reaction conditions favouring inversion at phosphorus are used then the (R)-menthoxy group of the prochiral starting material is substituted.The phosphinous acid ester can be converted, with partial racemization, into optically active Horner-phosphines.
