In nearly every total synthesis, silylating agents are employed in synthetic steps to protect sensitive functional groups. A Pt‐catalyzed hydrosilylation of various unsaturated substrates to prepare novel symmetrical and unsymmetrical disilazanes is described. The developed synthetic methodology is widely applicable and tolerates all manner of functional groups (e.g., amines, ethers, esters, halogens
在几乎所有的合成中,甲硅烷基化剂都用于合成步骤中,以保护敏感的官能团。描述了各种不饱和底物的Pt催化氢化硅烷化反应,以制备新颖的对称和不对称二硅氮烷。发达的合成方法学广泛适用,并能耐受所有形式的官能团(例如胺,醚,酯,卤素,硅烷等)。为了证明上述方法的价值,将单取代的1,1,3,3-四甲基二硅氮烷进一步选择性地转化为全新的不对称衍生物。
