摘要

The diyne (η5-C5Me5) Re (NO)(PPh3)(C CC CSiMe3) is elaborated to (η5-C5Me5) Re (NO)(PPh3)(C CC CC CSiR3)(R= Me, 3a; Et, 3b) by sequences involving n-Bu4N+ F− in aqueous THF to give (η5-C5Me5) Re (NO)(PPh3)(C CC CH)(91%), n-BuLi/CuI or t- BuOCu to give (η5-C5Me5) Re (NO)(PPh3)(C CC CCu)(4), and coupling with IC CSiMe3 (48%) or BrC CSiEt3 (84–65%). Complex 3b is similarly converted to (η5- ...
