Reaction of (η5-C5H5)2ReH with organic electrophiles: preparation of new biscyclopentadienyl rhenium compounds
Abstract
The title compound (1) reacts with methyl iodide and allyl bromide to give [(cp)2ReMe2]+(5)(cp =η5-C5H5) and [(cp)2Re(C3H6)]+(8) respectively; the dihydrido cation [(cp)2ReH2]+(10) reacts with diazomethane and excess of RCN to give the metallocarbene cations [(cp)2ReC(NHMe)R](11).
