toluenes and 1,2‐dichloroethane were also tested. The strong Lewis acids are able to promote the cleavage of C−Cl bonds in the presence of Et3SiH. The C−Cl bonds were converted into C−H bonds through hydrodechlorination reactions or, in the presence of benzene, into C−C bonds through Friedel–Crafts type reactions. The catalytic reactions show high conversions.
                                    我们报告了在中等条件下非均相催化剂
氯氟化铝(ACF)和高表面
氟化铝(HS-AlF 3)对
氯化
甲烷的活化作用。为了进行比较,还测试了
氯代
甲苯和
1,2-二氯乙烷。在Et 3 SiH存在下,强
路易斯酸能够促进C-Cl键的裂解。C-Cl键通过加氢脱
氯反应转化为C-H键,或者在苯存在下,通过Friedel-Crafts型反应转化为C-C键。催化反应显示出高转化率。
