The in air catalytic hydroboration of ketones and aldehydes with pinacolborane by an iron(II) coordination polymer (CP) is carried out under mild and solvent-free conditions. The precatalyst is highly active towards a wide range of substrates including functionalized ketones and aldehydes in the presence of KOtBu as an activator, achieving a high turnover number (TON) of up to 9500. Excellent chemoselectivity
所述在空气中通过铁(酮和醛与频哪醇的催化硼氢化II)配位聚合物(CP)在温和的和无溶剂的条件下进行。在KO t Bu作为活化剂的存在下,该预催化剂对包括功能化酮和醛在内的多种底物具有很高的活性,实现了高达9500的高周转率(TON)。与酮相比,该醛对醛的化学选择性也很高,与使用相同催化剂体系在惰性气氛下获得的结果形成鲜明对比。在此观察到的这种催化剂不仅高效,而且可循环使用至少5次,而不会失去其有效性。
