The chemistry of diphenylcarbene and fluorenylidene in cyclohexane was investigated. An examination of the product distributions, radical scavenging experiments and isotopic fractionation established that diphenylcarbene reacts with cyclohexane predominantly, if not exclusively, through its triplet state whereas fluorenylidene exhibits substantial chemistry from its low lying singlet state in addition

Selective Benzylic and Allylic Alkylation of Protic Nucleophiles with Sulfonamides through Double Lewis Acid Catalyzed Cleavage of sp<sup>3</sup>Carbon-Nitrogen Bonds
broad range of tosyl‐activated benzylic and allylic amines to give diversely functionalized products in good to excellent yields and with high regioselectivity. Furthermore, the cross‐coupling reaction of 1,3‐dicarbonyl compounds with benzylic propargylicamine derivatives has been successfully applied to the one‐step synthesis of polysubstituted furans and benzofurans.
