Isomerization of Secondary Phosphirane into Terminal Phosphinidene Complexes: An Analogy between Monovalent Phosphorus and Transition Metals

Secondary phosphirane complexes isomerize above 100 °C to give the corresponding terminal phosphinidene complexes, which can be trapped by alkenes and alkynes. This reaction is a rare instance of the isomerization of a PIII derivative into a PI derivative. It appears to mimic the reductive elimination of alkanes from transition-alkylmetal hydrides.

Cycloaddition reactions of 1-Alkyl-3,4,5-triphenyl-1,2-diphosphacyclopenta- 2,4-dienes in the coordination sphere of tungsten carbonyl

1-Alkyl-3,4,5-triphenyl-1,2-diphosphacyclopenta-2,4-dienes react with tungsten hexacarbo-nyl under the conditions of "indirect" replacement of the carbonyl group to give 1 : 1 complexes; [4+2] cycloaddition reactions of these complexes with maleic acid de
