Z-t-Butylbicyclo[3.1.O]hex-1-ene dimerizes primarily by a [o + IT] way, whereas 2,5-di-t-butylbicyclo[3.l.O]hex-1-ene undergoes an unusual hydrogen shift reaction to 1,3-di-t-butyl-2-methylcyclopentadiene. The presence of bulky substituents on or near the strained double bond of a bicyclo[3.l.O]hex-

β¦ Synopsis
Anions of allylmeldrum's acids reacted with phenyl(propynyl)iodonium salt to produce bicyclo[3.1.0]hex-1-enes as the reactive intermediates through cyclopropanation reaction to yield various dimerization products. Depending on the substitution pattern on the intermediates, various dimeric products were obtained.
