Addition–cyclization of a diallylmalonic acid ester and related compounds with per(poly)fluoroalkyl iodides using a trichlorolanthanide [LnCl3(cat.)]/Zn system
Abstract
A free-radical addition–cyclization of hepta-1,6-diene with per(poly)fluoroalkyl iodides initiated by LnCl3(cat.)/Zn yields per(poly)fluoroalkyl-substituted cyclopentanes, cis-disubstituted compounds predominating.
