Sur les conditions de formation des complexes des chloroalkylgallium (ClnR3−nGa) avec diverses bases de Lewis (R2O,R2S,R3N et R3P): étude par spectroscopie de RMN (1H)

From an NMR (¹H) study of various systems chloroalkylgallium/Lewis bases, it appears that the four types of gallium compounds (Cl_nR_3?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.
