Highly strained cyclic phosphine oxides can give anomalous results (inversion, C-P cleavage) on deoxygenation with HSiCl3 or C6H5SiH3.Use of the pyridine complex of HSiCl3 generally overcomes these difficulties, and a number of strained phosphines were prepared.Definite trends in 31P NMR shifts among saturated and unsaturated structures have been observed.Phosphines in the 7-phosphanorbornene system are particularly prone to form P(V) cycloadducts, which then decompose by a reverse McCormack-type of reaction.The reactivity is so high that even dienes form adducts with these phosphines.

Deoxygenation of the dimer of 1-phenylphosphole oxide gives the diphosphine, whose thermal decomposition provides a useful route to r-1-phenyl-c-3a,c-7a-dihydrophosphindole.In the gas phase in the temperature range 345-370 deg C the dihydrophosphindole un
