摘要：

Whereas diazotization of ap-2-(1,4-dimethyl-9-triptycyl)-2-methylpropylamine in benzene afforded expected hydrocarbons in addition to a small amount of 2-(1,4-dimethyl-9-triptycyl)-2-methylpropyl acetate, its sc-isomer gave 1,1,3-trimethyl-2,3,7,11b-tetrahydro-7,11b-omicron-benzeno-H-1-benzo[de]anthracene, and a larger amount of the acetate. The results provide unambiguous evidence that the 1-methyl group stabilizes the cation formed by diazotization.
