PREPARATION OF TRI-ALKYL GALLIUM OR TRI-ALKYL INDIUM COMPOUNDS

摘要

TrialkyI metal compounds, such as trialkyl gallium and indium compounds, are prepared in high yield and high purity by the addition of a trialkyl aluminum compound to a mixture prepared by adding a metal trihalide, e.g., GaCI3 or lnCI3, and a halide salt of a monovalent metal to an ionic liquid such as a molten salt of the formula M[AIRn Chi(4-n)] wherein M is a monovalent metal such as Li, Na, K or Cs, R is an alkyl group X is a halide and n is a number from 1 to 3, typically at temperatures of from 75 to 160° C.
