Selective mono-functionalization of 1,1,3,3-tetramethyldisiloxane (TMDSO) with vinyl and allyl metalloids via hydrosilylation reaction is reported. The activities of a number of transition metal catalysts in the reactions between TMDSO and selected unsaturated metalloids were determined, which permitted selection of the most efficient catalysts whose use led to selective formation of monofunctionalized
报道了通过氢化硅烷化反应用乙烯基和烯丙基类金属对1,1,3,3-四甲基二硅氧烷(TMDSO)进行选择性单官能化。确定了许多过渡金属催化剂在TMDSO和选定的不饱和准金属之间的反应活性,从而允许选择最有效的催化剂,这些催化剂的使用可通过区域选择性控制选择性形成单官能化二硅氧烷。分离所有产物,并通过NMR光谱和MS技术充分表征。
