    Description / Table of Contents: From an NMR (1H) study of various systems chloroalkylgallium/Lewis bases, it appears that the four types of gallium compounds (ClnR3-nGa) form adducts with trialkylamines, trialkylphosphines, ethers and sulphides, and that in all cases the 1:1 complex seems to be the only existing one. Its stability mainly depends on the number of chlorine atoms bound to the gallium and on the nature of the donor site.
    Notes: Une étude des conditions de formation des complexes résultant de l'addition des bases de Lewis usuelles (R2O, R2S, R3Net R3P) sur les chloroalkylgallium (ClnR3-nGa) a été réalisée à l'aide de la spectroscopie de RMN.Il apparaǐt que les seuls composés à se former à la température ambiante sont des complexes mettant en jeu 1 mole de base et 1 mole d'acide. Leur stabilité est gouvernée par le nombre d'atomes de chlore fixés sur le gallium et par la nature de l'atome donneur.
