摘要
A variety of polycycles can be synthesized via an intramolecular alkylation cyclization promoted by Ni(PPh3)(4) and NaHMDS. Mechanistic investigations support the catalytic nature of Ni-0 in the course of TEMPO scavenging experiments and its association with the substrate and NaHMDS to form an adduct by DOSY NMR.
