It is a strong base and a strong nucleophile.Application: Methyllithium solution (1.6M in diethyl ether) has been used for the asymmetric allylic alkylation (AAA) of allylic electrophiles in the presence of a chiral copper catalyst. This protocol leads to the C-C bond formation of tertiary and quaternary stereogenic centers with high enantioselectivity. It can also be used for the synthesis of (−)-salsolidine by reacting with 6,7-dimethoxy-3,4-dihydroisoquinoline in the presence of (−)-sparteine as a chiral ligand.RIDADR: UN 3394 4.3(4.2) / PGIWGK Germany: 1Flash Point(F): 1.4 FFlash Point(C): -17 CR Codes: 11-15-19-22-36/38-66-67S Codes: 16-26-43IOD Codes: F,XnSymbol: GHS02, GHS05, GHS07Signal Word: DangerHazard Statements: H225-H250-H260-H302-H314-H336Precautionary statements: P210-P222-P223-P231 P232-P370 P378-P422
