Abstract
Pyrolysis of solid complexes of aromatic diazo compounds with cyclomaltoheptaose (beta-cyclodextrin) yields either derivatives via insertion of carbene into hydroxyl groups. The distribution of the 2-, 3-, and 6-O-isomers indicates that the regioselectivity is moderate. The guest geometry is not as important as its size in determining the ratios of regioisomers. The origins of the regioselectivity are discussed.
