Abstract

Reactions between B2H6 or BH3· thf (thf= tetrahydrofuran) and nitriles RCN (R= Me, Et, But or CH2F), previously known to generate borazines (RCH2NBH) 3 have been found to generate also 25–37% yields of novel carboraza bicyclic systems related to dihydronaphthalene, H3B4N5 (RCH2) 4CHR, thus affording for the first time a direct route from commercially available acyclic reagents into mixed carbon–boron–nitrogen ...
