摘要：
The manganese(ii) complex [Mn(SiNSi)Cl2] (SiNSi = 2,6-[EtNSi(NtBu)2CPh]2C5H3N) is an efficient catalyst for the chemoselective C(sp)-H borylation of terminal alkynes. Aliphatic and aromatic alkynes with different substituents have been efficiently borylated. Mechanistic studies indicate that the precatalyst enters the cycle by reaction with HBPin (Pin = pinacolate), which plays a key role in enabling a high chemoselective process. The manganese(ii) complex [Mn(SiNSi)Cl2] (SiNSi = 2,6-[EtNSi(NtBu)2CPh]2C5H3N) is an efficient catalyst for the chemoselective C(sp)-H borylation of terminal alkynes.
