Abstract
The W(CO)5-phosphaalkene complexes 9a, b, and 11 take part in ene reac tions with the phosphaalkynes 1a-c to furnish the phosphinophosphaalke nes 10a-c and 12a, b containing the same metal fragment. In the reacti on of 13 with la, the ene product 14 undergoes partial isomerization t o the diphosphirane complex 15. Ene reactions of the P-silyl, C-silylo xy-substituted phosphaalkene complex 19 with 1a-c follow the normal co urse to yield 20a-c.
