## Abstract Regiochemistry and methylene transfer reactions in cycloadditions of aliphatic thiocarbonyl __S__‐methylides and thiobenzophenone are analyzed by ab initio [(U)HF/3‐21G\*] and DFT calculations [(U)B3LYP/6‐31G\*//(U)HF/3‐21G\* and (U)B3LYP/6‐31G\*]. The formation of regioisomeric 1,3‐dit

## Abstract **The cover picture shows** the potential energy diagram of methylene transfer from 4,4,5,5‐tetramethylcyclopentanethione __S__‐methylide to thiobenzophenone via a biradical intermediate which wins over a possible formation of regioisomeric cycloadducts. Methylene transfer reactions tog
