Addition and Cycloaddition Reactions of Allenyl Cations with Cyclic 1,3-Dienes
The zinc chloride catalysed reactions of 1,3-cyclohexadiene or 1,3-cycloheptadiene with propargyl chlorides 3 yield bicyclooctenes 1 and bicyclononenes 2, respectively.These reactions are suggested to proceed via stepwise -cycloadditi

ADDITION AND CYCLOADDITION REACTIONS OF ALLENYL CATIONS WITH VARIOUS CYCLOALKA-1,3-DIENES
Allenyl cations R-C=C=C(CH3)2(1+), generated in situ from propargyl chlorides and zinc chloride give monocyclic adducts or and cycloaddition products with various cycloalka-1,3-dienes.The mode of addition depends on R and the ring size of the
