Synthesis of 1H-Diphosphirene, Phosphorus-Carbon Cage and 2,3-Dihydro-1,2,3-Triphosphete Tungsten Complexes

Abstract:

New lH-diphosphirene and 2,3-dihydro-l,2,3-triphosphete tungsten complexes have been synthesized, by thermal decomposition of different 2H-azaphosphirene complexes in the presence of various phosphaalkynes. Novel phosphorus-carbon cage complexes were obtained, if a pentamethylcyclopentadienyl-substituted 2H-azaphosphirene complex and alkyl-substituted phosphaalkynes were employed.
