Homoleptic heavier alkaline earth amides, MN(SiMe3)2}2(THF)2 (M = Ca, Sr, and Ba) are reported as precatalysts for the dimerization of aldehydes to the analogous carboxylic esters (Tischenkoreaction). [reaction: see text].

Aromatic acyl fluorides can be reduced to the corresponding aldehydes in the presence of palladium complexes. Polymethylhydrosiloxane (PMHS) gives better results than hydrogen.
在钯络合物的存在下,芳族酰基氟可被还原为相应的醛。聚甲基氢硅氧烷(PMHS)的结果优于氢。

A novel catalytic system with a tripodal cobalt complex is developed for efficiently converting primaryalcohols to esters. KOtBu is found essential to the transformation. A preliminary mechanistic study suggests a plausible reaction route that involves an initial Co-catalyzed dehydrogenation of alcohol to aldehyde, followed by a Tishchenko-type pathway to ester mediated by KOtBu.
为了有效地将伯醇转化为酯,开发了具有三脚架钴络合物的新型催化体系。KO t Bu被发现对转型至关重要。初步的机理研究表明,可能的反应路线包括最初的共催化将醇脱氢成醛,然后由Tishchenko型途径由KO t Bu介导生成酯。
