摘要

Reactions of the aromatic halides chlorobenzene, 9-bromophenanthrene and chloro-p- xylene with lithium 2, 2, 6, 6-tetramethylpiperidide (LiTMP) in the presence of [Ni (η2- C2H4)(dcpe)](1) generated the corresponding η2-aryne complexes [Ni (η2- aryne)(dcpe)][aryne= C6H4 (2), 9, 10η-C14H8 (4) and 2, 3η-1, 4-Me2C6H2 (9)], which could not be isolated as pure compounds but were identified tentatively on the basis of ...
