coupling of the allyl radicals formed, particularly as no compounds containing CH2CHCHMeTe are recovered after partial pyrolysis. The products can be fitted to a purely statistical model in which the reactivity ratio of the primary to secondary allyl is ca. 0.63:0.37. The statistical fit is taken to indicate that mechanisms other than that involving homolytic fission and freeradical coupling play a negligible

The dialk-2-enylzinc compounds I–III react slowly at 20 to 50°C by addition of the ZnC bond to the CC bond of an alk-2-enyl group to give oligomers from which the alkenes XIII–XV are released on hydrolysis. For I–III homolytic cleavage of the ZnCallyl bond, followed by coupling of the allyl radicals to give the alkadienes V–VII, IX and XI predominates above 50°C. IV decomposes mainly homolytically
