Direct Substitution Reaction of Phenylethyl Bromides

  • Published : 1973.03.01

Abstract

Halongen exchange reactions of phenylethyl bromides have been studied in acetone at 25$^{\circ}$and 35$^{\circ}C$. Results show that the reaction proceeds by a typical S$_{N}$2 path, and steric crowding effect in 1-phenylethyl bromide gives large variation in the activation parameters for chloride exchange.

25$^{\circ}$및 35$^{\circ}C$의 아세톤 용액에서 부롬화 훼네틸들의 할로겐 교환반응을 연구하였다. 결과로 이 반응은 전형적인 SN2형 반응이고 염소 교환의 경우 1-부롬화 훼네틸의 입체 반해작용으로 활성화 파라메터에 큰 변화를 가져옴을 알았다.
