BIS(TRIMETHYLSILYL) MALONATE Chemical Properties,Uses,Production
Chemical Properties
clear colorless to straw colored liquid
Uses
Bis(trimethylsilyl) malonate was used as cyclocondensation agent in cyclocondensation reactions. It was also used in the preparation of β-keto acids and methyl ketones.
General Description
Bis(trimethylsilyl) malonate is precursor for metal-organic chemical vapor deposition (MOCVD) of HfO2 and ZrO2 thin films. It undergoes acylation reaction with acid chlorides and acyl carbonates in the presence of triethylamine and magnesium or lithium salts to give β-keto acids or methyl ketones.
Synthesis
Bis(trimethylsilyl) Malonate can be easily prepared from malonic acid by a number of silylation procedures. It is a reagent useful in the synthesis of β-keto acids and methyl ketones.
