| 英文摘要 | Herein, we disclose the first manganese-catalyzed hydrosilylation of alkynes featuring diverse selectivities. The highly selective formation of E-products was achieved by using mononuclear MnBr(CO)(5) with the arsenic ligand, AsPh3. Whereas using the dinuclear catalyst Mn-2(CO)(10) and LPO (dilauroyl peroxide) enabled the reversed generation of Z-products in good to excellent stereo-and regioselectivity. Such a way of controlling the reaction stereoselectivity is unprecedented. Mechanistic experiments revealed the dichotomy of manganese catalysis via organometallic and radical pathways operating in the E- and Z-selective routes, respectively. |
