Beatriz Andres,Raul Poler,Raquel Sanchis with SMe. cations to yield first η.-thiocarbene complexes and then dithiatungstabicyclobutane complexes. Comparable η.-phosphinocarbene complexes are obtained on mild thermolysis of tungstaphosphabicyclo-butanone cations.

Dario Antonelli,Sergey Astanin,Giulia Brunoum complex (1); oxidation of (3a-f) with Ce. leads to the corresponding γ-lactones. The extension of the above reactions to oxetane allowed the synthesis of the new pentacarbonyl(2-oxacyclohexylidene)chromium complex. It is noteworthy that the oxetane ring opening occurs only in the presence of BF..Et.0.

Collaboration in a Hyperconnected Worldel synthesis of vinylidene complexes involves reaction of 1-halogeno-l-silylalkenes with unsaturated metal fragments. In the latter reaction butatriene complexes are formed instead, if an excess of alkene is used. On grounds of model reactions, a possible mechanism for the coupling of two vinylidene units is discussed.

Collaboration in a Hyperconnected World of CpMo(SnPh.) (=CHPh) (CO). migrates to the alkylidene forming an η.-benzyl complex. We conclude that a number of X to carbene or alkylidene migrations proceed at rates suitable for an extensive general study of the phenomenon.
