摘要：

(Chemical Equation Presented) All together now: Pd0/tBu 3P-catalyzed annulative tandem reactions of 1,2-dihalobenzenes were carried out with hindered Grignard reagents. This new type of tandem reaction is believed to occur through cross-coupling followed by cyclization with C(sp 3)-H bond activation as the key step and allows one-step access to potentially useful substituted fluorenes in high yield from readily available 1,2-dibromobenzenes and 1-bromo-2-iodobenzene. © 2006 Wiley-VCH Verlag GmbH & Co.
