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

Stannylated allylic substrates are versatile building blocks for organic synthesis. Pd0-catalysed coupling reactions of 2-stannylated allyliccarbonates, acetates and phenoxides with amines, malonates, phenoxides, imides and distannanes provide the corresponding substituted allylic compounds, which are suitable for subsequent modifications including Stille coupling reactions. The reaction mechanisms
