Yield: 90%

Reaction Conditions:

Reflux;

Steps:

1 Example 1
352 g (2.0 mol, 1.0 eq.) of GaCI3 (ex MCP) were poured into a 1 I two-neck round- bottom flask equipped with a distillation column, stirrer and a thermocouple. 447 g (6.2 mol, 3.1 eq.) TMAL were added dropwise to GaC . The mixture was gradually heated to reflux temperature. The distillate was collected into a cooled receiving flask (-5°C) with a top temperature of 56-58°C. TMG was isolated in a 90% yield (206 gram) with a purity of >99% based on 1H NMR analysis.
