Applicazioni

A double Suzuki cross-coupling protocol has been devised as a practical route to a variety of terphenyls. Good chemoselectivity was observed. Unsymmetrically substituted triphenylenes were also easily prepared. A double Suzuki cross-coupling protocol has been devised as a practical route to a variety of terphenyls and triphenylenes.
