Photochemical synthesis of coupled boranes and carbaboranes
Abstract
The mercury-sensitised photochemical reactions of boranes or carbaboranes at 2537 Å have been found to be a convenient method of synthesising the corresponding boron–boron coupled boranes or carbaboranes; the synthesis of 3,3′-(2,4-C2B5H6)2 and 2,2′-(B5H8)2 is described.
