Slobodin, Ya. M.,Ashkenazi, L. A.,Shustareva, T. K.

, p. 1070 - 1073 (2007/10/02)

Phase-catalyzed reaction of dichlorocarbene with tricyclo2,6>deca-3,8-diene gives either a mono- or a diadduct, depending on reactant proportions.The first dichlorocarbene adds to form a dichlorocyclopropane moiety, and addition of the second is accompanied by rearrangement with enlargement of the norbornane ring to give a mixture of approximately equal amounts of two isomers which differ in the position of the double bond.
