Abstract
Absolute rate constants of reaction of chlorophenylcarbene, bromophenylcarb ene, and chloro-p-nitrophenyl-carbene with tetramethylethylene (TME; k(TME) ) are similar in alkane solvent, Freon-113, benzene, tetrahydrofuran, and a cetonitrile. Solvation of the carbenes has little influence on k(TME) Stron g specific solvation which impedes cycloaddition reactions of the arylhaloc arbenes with TME is not found with these carbenes, but the existence of wea kly bound complexes with spectra and kinetics similar to those of free carb enes cannot be ruled out.
