N. Tokitoh et al., ABNORMAL REACTION OF AN ARYL AZIDE CONFINED IN A CALIX[6]ARENE SKELETON, Journal of the Chemical Society, Chemical Communications, (18), 1995, pp. 1899-1900
Photolysis of an aryl aide embedded in a m-phenylene-bridged p-tert-bu
tylcalix[6]arene 2 results in the formation of unusual reaction produc
ts 3 and 4 via the transannular addition reaction of an initially form
ed nitrene intermediate; the molecular structure of 4 was determined b
y X-ray crystallographic analysis.
