Аннотация: The reactions of imino phenols 3,5-But2-2-HOC6H2CH=NX (X = 8-C9H6N, 2-MeO-5-MeC6H3 and 2-PhOC6H4) with Sc(CH2SiMe3)3(THF)2 in toluene proceed with silane elimination and reductive alkylation of the C=N group affording dimeric base-free monoalkyl scandium complexes. X-ray analysis of the two complexes revealed their dimeric structures due to μ-bridging amidophenolato dianions. The complexes catalyze hydrophosphination of styrene, phenylacetylene and tolane with Ph2PH as well as dehydrogenative coupling of anisole with hydrosilanes.

Ключевые слова: scandium, alkyl complexes, catalysis, hydrophosphination, dehydrocoupling, organosilicon compounds, organophosphorus compounds.
