Abstract
A system and method of making a silylcarbonate compound, the method including reacting trialkylsilylalcohol with alkyl chloroformate in the presence of a base at an elevated temperature to form the silylcarbonate compound.
Claims19
A method of making a compound comprising:
- mixing a solvent, trialkylsilylalcohol, alkyl chloroformate, and a base to form a reaction mixture;
- heating the reaction mixture to form a heated mixture comprising the compound having a structure of Formula (I);
- wherein
- R1 is CH2, CH2CH2, or CH2CH2CH2;
- R2 is C1-C4 alkyl, C2-C4 alkenyl, a substituted aryl, or an unsubstituted aryl;
- and
- R3 is an alkyl.
