INTRAMOLECULAR GAMMA-C-H INSERTION VS OLEFIN CYCLOADDITION IN 4-METHYLENE-2-ADAMANTYLIDENE AND 8-METHYLENE-2-NORADAMANTYLIDENE

8-Methylene-2-noradamantylidene inserts readily into the y C-H bond giving 6-methylene-2, 4-didehydronoradamantane rather than the olefin-cycloaddition product, while its higher homologue 4-methylene-2-adamantylidene reacts exclusively by intramolecular cycloaddition to the olefinic bond yielding 2, 4-methano-2, 4-didehydroadamantane, a [3.1 .I .]propellane.
