Abstract
The cyclic oxacarbene complexes [Mo{CCH2(CH2)(n)CH2O}L(2)(eta-C7H7)]PF 6 [n = 1 or 2; L = CO, L(2) = Ph(2)PCH(2)PPh(2) or Ph(2)PCH(2)CH(2)PPh (2) (dppe)] have been synthesised and the 1-oxacyclopent-2-ylidene lig and in the derivative n = 1, L(2) = dppe shown to adopt a horizontal o rientation; the crystallographically characterised, hydroxyvinylidene complex [Mo{C=C(H)CH2CH2CH2OH}(dppe)(eta-C7H7)]PF6 is an isolable inte rmediate in the formation of [Mo{CCH2(CH2)(2)CH2O}(dppe)(eta-C7H7)]PF6 .
