Anyone got any tips for getting thf-free dibutyl magnesium? Got three bottles of it with thf in now 😓

@mattd_t And often some AlEt3... we always resorted to using Mg(CH2SiMe3)2 which you can make and sublime so that it is completely donor free!

@mattd_t Ooohhh I just bought that and thought the THF must have come from another reagent

@mattd_t I think all commercial stuff has about 1% THF, sometimes labelled, sometimes not. Probably make it yourself is the only option to be sure.

@mattd_t Have a similar problem these days, all I can suggest is an alternative supplier or making it yourself, unfortunately.

@mattd_t We had the same problem, as you might remember. It doesn’t mention there is THF on the product label
