INTERACTION OF DISTANNANES WITH SUBSTITUTED ORTHO-QUINONES

The reactions of distannanes with 3,5- and 3,6-di-t-butyl-1,2-benzoquinone have been investigated. It has been shown that the primary step of the process is a one-electron transfer from distannane to quinone. The main reaction products are formed tin-containing semiquinones by elimination of the organic substituent (R) from the tin atom. Elimination of radical R is the result of intramolecular coordination of oxygen with the tin atom in semiquinone and it occurs with the participation of the second moiety without the removal of the kinetically independent R into solution. © 1979.
