On the chemospecificity of the double stannylation and double hydrostannation of terminal alkynes by the tributylstannane in the presence of thiol
摘要:
The mechanism of competing double stannylation and double hydrostannation reactions of terminal alkynes in the presence of arylthiol has been investigated. The data reveal the radical character of the reactions, the importance of the [tributylstannane/arylthiol] system as radical initiator at ambient temperature and the occurrence of a polarity reversal catalysis process in the double hydrostannation pathway.

Single-atom-site (SAS) catalyst, as a highly reactive heterogeneous catalytic system, is one of the effective tools for complex organic synthesis. However, excessive attention on the catalysis and regulation of metal atoms has led to the neglect of the role of supports and ligands. Here, we employed a P-doped porous organic polymer as a support, as well as a ligand in the developed Pd SAS catalysts. The enrichment
