Abstract
Abstract A series of triphenolsilane-coordinated molybdenum (VI) propylidyne catalysts has been developed, which are resistant to small alkyne polymerization and compatible with various functional groups (including phenol substrates). The catalysts remain active in solution for days at room temperature (months at− 30 C). The catalysts are also compatible with 5 Å molecular sieves (small alkyne scavengers), and have enabled the ...
