1,1,1-trichloro-2-hydroxy-4-methyl-pentene-3 (1b) was chlorinated to afford tri- and tetra-chlorinated compounds 2,3,4.Compounds 2 and 3 were transformed by reductive dechlorination into 1,1-dichloro-4-methyl-1,3-pentadiene.Another route starting from the same alcohol or its isomer was also developed.
