英文摘要	titanocene complexes combined with nanometer-size sodium hydride are extremely active and selective catalysts for the hydrogenation of terminal alkenes under normal pressure. the initial turnover frequencies (tofinitial) may reach 100-300 s(-1) in the hydrogenation of 1-hexene. the highest catalytic efficiency turnover (to) reaches 1.5 x 10(5) in 2 h for the hydrogenation of styrene. these catalytic systems exhibit specific selectivity toward alkene substrates. only terminal alkenes can be hydrogenated. no isomerization of carbon-carbon double bonds occurs during hydrogenation. a suitable substituent on the cyclopentadienyl ring of titanocene and the use of nanometric sodium hydride are key factors in the high efficiency of these catalytic systems.
