Palladium-catalyzeddoublecross-couplingreactions of 1,1-bis(pinacolato)borylalk-1-enes with 2,2′-dibromobiaryls and of 9-stannafluorenes with 1,1-dibromoalk-1-enes have been demonstrated to serve as new synthetic methods for dibenzofulvenes.

A copper-catalyzed decarboxylative coupling reaction of potassium alkynyl carboxylates with 1,1-dibromo-1-alkenes was developed for the synthesis of unsymmetrical 1,3-diyne and 1,3,5-triyne derivatives. Diverse aryl, alkenyl, alkynyl, and alkyl substituted 1,1-dibromo-1-alkenes can react smoothly with aryl and alkyl substituted propiolates to produce unsymmetrical 1,3-diynes and 1,3,5-triynes with high selectivity and good functional group compatibility.

The X-ray structure of perfluorophenyl substituted Y-enyne 1 reveals a face-to-face stacking interaction between phenyl and perfluorophenyl groups of different molecules resulting in a high order in the solid state. Acetylene-arene and acetylene-fluorine interactions also contribute to the high order stacking. The X-ray structure suggests a distorted conjugation of the chromophore. (C) 2001 Elsevier Science Ltd.
