Abstract
- The reactions of the monomeric phosphanylboranes Ph2P-BH2 ·NMe3 ( 1a) and tBuHP-BH2 ·NMe3 ( 1b) with the main group Lewis acids BH3 and BBr3 yield the adducts H3B ·Ph2P-BH2 ·NMe3 ( 2a) and H3B · tBuHP-BH2 ·NMe3 ( 2b), Br3B ·Ph2P-BH2 ·NMe3 ( 3a), and Br3B · tBuHP-BH2 ·NMe3 ( 3b). All these compounds were completely characterized by single-crystal X-ray structure analysis, NMR and IR spectroscopy as well as mass spectrometry and DFT computations. The secondary and tertiary phosphines 1a and 1b behave as classical Lewis bases to coordinate B X3 ( X = H, Br) as terminal groups. [ABSTRACT FROM AUTHOR]
