CH3I 了,不过也是剧毒品,呵呵还有一好东西,不知对你反应行啵,<对甲苯磺酸甲酯 试试吧

The least inexpensive methylating reagent is Meerwein's salt. Me3OBF4. It's a solid so you should be able to handle it easily. Methyl triflate could be another option. Althohght many methylating electrophiles are available, their hard/soft properties need to match with that of your nucleophiles.

CH3I 是可以的,不过太贵!硫酸二甲酯有神经毒性,带上防毒面具.手套就可以了

使用硫酸二甲酯或者碘甲烷的时候在旁边准备点氨水，用过的仪器用氨水洗一下，反应完全后也应该向其中加入一些氨水处理过量的硫酸二甲酯或者碘甲烷，废液经氨水处理后再排放

可以试用碳酸二甲酯代替

碳酸二甲酯相对比较安全、环保，不过碳酸二甲酯比硫酸二甲酯贵多了
