Nitrobenzyl benzothiazol-2-yl sulfones and nitrobenzyl 1-phenyl-1 H -tetrazol-5-yl sulfones react with chlorides of aromatic acids to form β-acyl derivatives. These products undergo the Smiles rearrangement resulting in the formation of the corresponding nitrophenyl arylacetylenes in 50-60% overall yields (approx. 75% per step). Sulfones bearing CF 3 or CN groups instead of a NO 2 substituent form mixtures of the acetylenes in moderate yields and benzyl aryl ketones in yields above 40%.

In the presence of catalytic amounts of RhH(CO)(PPh3) 3 and 1,2-bis(diphenylphosphino)benzene (dppBz), acyl groups were transferred between benzyl ketones and thioesters/aryl esters. The rhodium complex catalyzed the cleavage of keto
