Distannoxane catalysts effect acylation of alcohols by action of esters and acetic anhydride. In particular, use of enol esters provides an extremely useful method. Primary alcohols are acylated in preference to secondary ones as well as phenol. Both acid- and base-sensitive functional groups remain intact. Especially unique is the discrimination of thio function which is completely tolerant under
Cr2O3 supported on sulfated silica catalysts exhibit excellent performance for the oxidative dehydrogenation of ethane into ethylene by carbon dioxide, giving 90% selectivity towards ethylene at 60% ethane conversion at 650 °C.
Various olefins are hydrated with molecular oxygen (oxidant) and a secondary alcohol (reductant) in the presence of a catalytic amount of bis(trifluoroacetylacetonato)cobalt(II) in good yields.
在催化量的双(三氟乙酰丙酮合)钴 (II) 存在下,各种烯烃与分子氧(氧化剂)和仲醇(还原剂)以良好的产率水合。
