Description

MilliporeSigma Sigma Organics products encompass a wide range of quality reagents, solvents, catalysts, and building blocks for organic synthesis. From benchtop discovery to process development and scale-up, Sigma Organics solutions are built to meet the needs of synthetic chemists.

Lithium tert-butoxide (LiOtBu) is a weakly basic and nucleophilic alkali metal oxide commonly used as an initiator for anionic polymerization.Other synthetic applications: In combination with potassium diisopropylamide, LiOtBu can be used to deprotonate 1-(phenylseleno) alkenes and bis (phenylseleno) acetals.LiOtBu can mediate the +a-alkylation reaction of ketones with primary alcohols in the absence of any transition metal catalyst.LiOtBu is an effective base for the synthesis of 3,4,5-trisubstituted 3H-oxazol-2-ones and 3,4-disubstituted (Z)-oxazolidin-2-ones from substituted propargyl alcohols and aryl/alkyl isocyanates using DMF as a solvent.
