Lithium Hexamethyldisilazide (LHMDS; CAS 4039-32-1) is a lithium amide with molecular formula LiN[Si(CH3)3]2. It is supplied as a typical 25% solution in THF. LHMDS is commonly used as a strong non-nucleophilic base for selective deprotonation. Due to the low nucleophilicity it is often used in enolizations of ketones, aldehydes and esters. LHMDS reacts readily with moisture and air and should be…
