Abstract: | 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. |
