A FACILE METHOD FOR DEBROMINATION OF VICINAL DIBROMIDES
《Chinese Chemical Letters》1991年第2期123-124,共2页Qi ZHONG Jian Guo SHAO Chang Qing LIU Rong Jian LU Chemistry Department,Yangzhou Teachers College,Yangzhou,225002 
In the presence of equimolar triethylamine,vicinal dibromides were found to be easily debrominated by dibutyl telluride,forming the co- rresponding olefins.
