Abstract: Aluminum hydride cations, [LAlH]+[HB(C6F5)3]- (1) and [LAlH]+[B(C6F5)4]- (2), and the methyl aluminum cation, [LAlMe]+[B(C6F5)4]- (3) (L = [{(2,6-iPr2C6H3N)P(Ph2)}2N]), due to their electronic and coordinative unsaturation at the Al center, exhibit high Lewis acidity and have… read more here.

DOI: 10.1021/acs.orglett.1c00230
Abstract: We describe a simple and efficient procedure for nucleophilic borylation of imines in the absence of a photoredox catalyst. Visible light irradiation of an acetonitrile solution of an imine, an NHC-borane, and diphenyl disulfide (10… read more here.

DOI: 10.1039/d3nj01979a
Abstract: A crucial step in the formation of mono-aminoboranes (R2N-BH2) from the corresponding imine-BH3 adducts, under mild reaction conditions, is the 1,3-hydride shift. We offer experimental and theoretical insights into this... read more here.
