Tributyltin hydride reaction of the tricyclo[5.2.1.0(2, 6)]decenes 3, 11, 15 bearing the 1,4-halo carbonyl system has been shown to involve C-C bond cleavage as the major reaction path leading to bridged eight membered rings in contrast to reduction of the carbon-halogen bond in 7.

Tributyltin hydride reaction of the tricyclo[5.2.1.0(2,6)]decenes 5, 16 and 23 bearing a halo-carbonyl moiety has been shown to involve C-C bond cleavage as the major reaction path leading to bridged eight-membered rings 12, 17 and 24. In contrast the halo-carbonyl derivatives 8, 33 and 36 undergo only reduction of the carbon-halogen bond. The ring cleavage observed has been attributed to the release of strain arising from nonbonded interaction as well as strain associated with norbornene.
