Triethy laluminium

In 1966, Clemens reported one of the very first syntheses of ambiphilic derivatives, namely the phosphine-alanes la,b, by aminolysis of triethy-laluminium with the corresponding amino-phosphines Ph2PNHR (Scheme l).8 Compounds la,b were obtained in good to excellent yields, and characterized by IR, 31P and H NMR spectroscopy as well as... 

Oxetane (oxacyclobutane) has been copolymerised successfully with carbon dioxide to give poly(trimethylene ether-carbonate) in the presence of the triethy-laluminium water acetylacetone (2 1 1) catalyst (Table 9.4) [scheme (35)]. The carbon dioxide content in the copolymer produced was ca 20 mol.-%. Attempts to carry out oxetane/carbon dioxide copolymerisation with the diethylzinc water (1 1) catalyst failed to give any copolymer [245],...
