A number of these undergo X to carbene migration, typically resulting in complexes . Some of these products rearrange further. We also find that the SnPh. group

Script Analysis for CollaborationWe also discuss our recent results on the successful cyclization of two alkynes and a carbene moiety. This latter chemistry involves cobaltacyclopentadiene complexes which are converted to η.-cyclopentadiene compounds upon reaction with ethyl diazoacetate.

Preparing the Collaborative Classed that the C-F bond in . readily reacts with HBF. in the presence of protic nucleophiles such as alcohols and thiols to give carbene complexes. The intermediacy of an hydridodifluorocarbene species has been confirmed by low-temperature NMR spectroscopy.The X-ray structure of an hydridocarbene complex of Pt(II) is also reported.

Important new classes of compounds including reactive,anionic η.-ketenyl and carbyne complexes are produced /1–8/.

Arda Gezdur,Jyotirmoyee Bhattacharjyaarbenes by undergoing nucleophilic addition to the carbene carbon to give rather unique carbene-adduct products. Although type D complexes do not contain a carbene group, an iron derivative is proposed to exist in equilibrium with the carbene-mercaptide form:..H NMR and chemical evidence supports this proposal.
