摘要：

Highly regio- and stereoselective borylstannylative carbocyclization of diynes 2a-f with the borylstannane 1 are efficiently catalyzed at room temperature by a series of palladium complexes such as Cl2Pd(PPh3)(2), Cl2Pd[P(o-tolyl)(3)](2), Pd(PPh3)(4), and Pd(dba)(2), giving 1-(borylmethylidene)-2-(stannylmethylidene)cycloalkane derivatives 3a-f in high yields. A 1,6-enyne (2g) also reacts similarly to afford a high yield of the corresponding cyclized product 3g.
