Synthesis and Structure of 1,4-Dihydro-1,4-diphosphinines and 1,4-Dihydro-1,4-phospharsinines

The cyclizing addition of phenylphosphane or phenylarsane to tert-butyl(benzyl, diethylamino)diethinylphosphane (14) with formation of the 1,4-dihydro-1,4-diphosphinines 11a - d and 1,4-dihydro-1,4-phospharsinines 12a - d, resp., occurs by a radical mecha
