A novel metal-free intramolecular Bronsted-acid-catalyzed domino deprotection–hydrosilylation with hydrosilanes has been developed, and the unexpected Bronsted-acid-catalyzed intermolecular hydrolytic oxidation to functional siloxanes was described for the divergent and facile synthesis of functionalized siloxanes containing aldehyde motifs. We propose that these reactions proceed via neighboring acetal-assisted
一种新型的无金属分子内布朗斯台德酸催化多米诺脱保护 - 氢化硅烷与氢硅烷被开发出来,并且描述了出人意料的布朗斯台德酸催化分子间水解氧化为功能性硅氧烷,用于发散和轻松合成含有醛基序的功能化硅氧烷。我们建议这些反应是通过相邻的缩醛辅助的 Si-H 键活化进行的。此外,相关反应有望为有机催化功能有机硅化合物的开发和应用开辟进一步的机会。
