The Interaction of Donors with Diethyl Aluminium Chloride. IV. 13C-N.M.R.-Investigations on the Degree of Complex FormationEt2AlCl has some importance for the initiation of cationic polymerizations where its activity can be influenced by the addition of donor compounds. To enlight the elementary processes quantitative 13C-n.m.r. spectroscopic investigations of the model systems Et2AlCl/pyridine and piperidine, respectively, were carried out. Detailed information are given with regard to the molar ratios of acceptor and donors. The formation of an ionic intermediate complex was observed. The degree of complex formation is higher for piperidine than for pyridine. In the case of pyridine a 1:1 complex is formed. With piperidine a complexation with higher coordination must be assumed.
