Directed ortho metalation - suzuki cross coupling connections. Convenient regiospecific routes to functionalized m- and p-teraryls and m-quinquearyls
摘要:
Rapid access to a variety of substituted m- and p- teraryls and m- quinquearyls (Table) via Pd-catalyzed, one-pot, sequential and 1:2 cross coupling of aryl halides with aryl boronic acids, both available by metal-halogen exchange or directed ortho metalation tactics, is described.
