Organotitanium oxides as Lewis acidic supports of metal carbonyl species: [{Ti3(η5-C5Me5)3(µ-O)3Me}{(µ-OC)M(CO)2(η5-C5H5)}2](M = Mo, W)
Abstract
Reaction of [{Ti(η5-C5Me5)(µ-O)}3(µ3-CH)]1 with [M(η5-C5H5)(CO)3H](M = Mo, W) leads to the formation of Lewis acid carbonyl adducts [{Ti3(η5-C5Me5)3(µ-O)3Me}{(µ-OC)M(CO)2(η5-C5H5)}2]4, 5 showing the transformation of the µ3-methylidyne group into a Me group through the µ-methylene intermediates [{Ti3(η5-C5Me5)3(µ-O)3(µ-CH2)}(µ-OC)M(CO)2(η5-C5H5)]2, 3.
