The reaction of the anionic alkyl complexes of chromium and tungsten, NEt4⁺<(CO)5M>- (M = Cr, R = OMe; M = W, R = OMe, Me, H) with HBF4*Et2O yields isolable, strongly electrophilic benzylidene(pentacarbonyl) complexes, (CO)5M=CH(p-C6H4R); thermolysis of the tungsten compounds gives μ-benzylidene(pentacarbonyltungsten) complexes, <(CO)5W>2<μ-CH(p-C6H4R)>.
