Abstract
A novel N,N,N-trimethyl-[1,1'-biphenyl]-2-methanaminium compound is subjected to a rearrangement reaction to give a 3-dimethylaminomethyl-2-methyl-[1,1'-biphenyl] compound which is then converted to the corresponding 3-halomethyl-2-methyl-[1,1'-biphenyl] compound. The halomethyl compound is an intermediate for pyrethroid and related insecticides having the alcohol moiety derived from a 2-methyl-[1,1'-biphenyl]-3-methanol.
