Reactions over metal catalysts. Part I. The stereochemistry of hydrogenolysis of 3-acetoxynortricyclene
Abstract
Hydrogenolysis of 3-acetoxynortricyclene gives a mixture of acetoxynorbornanes in which 7-acetoxynorbornane predominates. When deuterium is used in the reaction, the n.m.r. spectra of this product shows a stereospecific deuterium incorporation into 2,6-endo-positions. The reactions of acetoxyquadricyclene and 7-acetoxynorbornadiene with deuterium are also discussed.
