Title (EN) PREPARATION OF TRI-ALKYL GALLIUM OR TRI-ALKYL INDIUM COMPOUNDS
(FR) PRÉPARATION DE COMPOSÉS GALLIUM DE TRIALKYLE OU D'INDIUM DE TRIALKYLE
Abstract: front page image
(EN)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 Χ(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.
(FR)La présente invention concerne la préparation de composés métalliques de trialkyle, comme des composés gallium et d'indium de trialkyle, à haut rendement et de grande pureté par l'adjonction d'un composé aluminium de trialkyle à un mélange préparé par adjonction d'un trihalogénure de métal, par ex., GaCI3 ou lnCI3, et d'un sel d'halogénure d'un métal monovalent à un liquide ionique comme un sel fondu de formule M[AIRn Χ(4-n)] où M est un métal monovalent tel que Li, Na, K ou Cs, R est un groupe alkyle, X est un halogénure et n est un nombre allant de 1 à 3, classiquement à des températures allant de 75 à 160 °C.
