the trichlorides of boron, aluminium, and gallium, germanium tetrachloride, stannic chloride, and antimony pentachloride. New complexes were isolated from the reactions with the latter two acceptors and with boron trichloride having stoicheiometries SnCl4,2L, SbCl5,L, and BCl3,L, respectively. With titanium tetrachloride, three types of adduct of tetrazaborolines were prepared. Compounds of the stoicheiometries

Two series of complexes of titaniumtetrachloride and 1,4,5-trimethyltetrazaboroline with aromatic hydrocarbons have been prepared. These have the general formulae 4TiCl4,2Me2N4BMe,L (L = benzene, p-xylene, and naphthalene) and 4TiCl4,2Me4N4BMe,2L (L = toluene and o-xylene). Condensed-phase heats of formation of the complexes, measured calorimetrically, are 265–283 kJ mol–1.
