Diphenyl(3-methyl-2-indolyl)phosphine (C(9)H(8)NPPh(2), 1) gives stable dimeric palladium(II) complexes that contain the phosphine in P,N-bridging coordination mode. On treating 1 with [Pd(O(2)CCH(3))(2)], the new complexes [Pd(mu-C(9)H(7)NPPh(2))(NC

A rational approach towards the borylative ring-opening of vinylepoxides and vinylaziridines, by the in situ formed MeO(-)→bis(pinacolato)diboron adduct, has been developed. The enhanced nucleophilic character of the Bpin (sp(2)) moiety from the re

Based on preliminary studies it is claimed that an in situ generated MeO-—bis(pinacolato)diboron adduct combined with the chiral phosphine allows the asymmetric synthesis of title compounds (III) via enantioselective nucleophilic boron addition to

Boron compounds have been traditionally regarded as “Lewis acids” preferring to accept electrons rather than donate them in the course of their reactions but current examples of unusual reactivity between tricoordinated boranes and electrophilic

Organocatalytic nucleophilic pinacolboryl addition from in situ generated MeO(-)→ B(2)pin(2) to C=N double bond can be performed enantioselectively with the aid of chiral phosphines, which promote enantiofacial differentiation in the course of the
