There are disclosed a composition comprising
(E)-1,4-dibromo-2-methyl-2-butene and
(Z)-1,4-dibromo-2-methyl-2-butene, wherein the ratio of the E isomer to the total amount of the E and Z isomers is 0.9 or more; a process for producing the same and a process using the same to produce an allyl halide compound of formula (1):
1
wherein X denotes a bromine atom,
Y denotes an ArS(O)
2
group or an RCOO group,
wherein Ar denotes an aryl group which may be substituted and R denotes a hydrogen atom, a lower alkyl group or an aryl group which may be substituted, and
the wavy line means that the derivative is a mixture of an E or Z geometrical isomer.
