Starting Material 2,7-Dihetero-isotwistanes

The observed decrease of rearrangement can be summarized by the following sequences [Pg.52]

Isotwistanes of the type G 40 [leaving group R -C(10) R -C(4) = substituent], although they are intermediates in the reactions of adamantanes G 36, are immediately further transformed under the applied reaction conditions - -G 49 (onium ion) - G 50 (isotwistane) + G 51 (twistane) (see 3.2.2.2.). In isolated form such compounds G 40 have not yet been used as starting materials. [Pg.52]
