Abstract
Dicarbonyl(cyclopentadienyl)carbyne complexes of tungsten display a distinct nucleophilic character of the tungsten carbyne carbon triple bond. Cp(CO)2W≡CNEt2 reacts with protic acids to give diethylaminocarbene complexes. The corresponding alkyl and aryl carbyne complexes react in a stepwise manner with SMe+ cations to yield first η2-thiocarbene complexes and then dithiatungstabicyclo[1.1.0]butane complexes. Comparable η2-phosphinocarbene complexes are obtained on mild thermolysis of tungstaphosphabicyclo[1.1.0]-butanone cations.
