Abstract

1,3-BENZODITHIOLIIJM ION MEDIATED ANNULATIONS k James H. Rigby, Atul Kotnis, James Kramer Department of Chemistry Wayne State University Detroit, Michigan 48202 Summary: A mild and selective method for cyclizations onto aromatic systems using 1,3_benzodithiolium ions is described. The Friedel-Crafts reaction continues to play an important role in annulation chemistry. 1 The utility of this reaction, however, is sometimes limited by the strongly ...
