Sulfoxides
Q 0600
33- 097
A New Synthesis of Allyl Sulfoxides via Nucleophilic Addition of Sulfinyl Carbanions to Group 6 Fischer Carbene Complexes. — Allyl sulfoxides are generally obtained in better yield when tungsten complexes are used as acceptors. Attempts to accomplish the reaction of alkyl carbene complex (VIII) with sulfinyl carbanion are unsuccessful. Treatment of carbene complexes with α-lithiosulfinyl carbanions leads to
enol ethers (XI)/(XII) and (XIV)/(XV) in good yield after warming, but as Z/E mixture.
