Реферат:
The reaction of dicyclopropylacetylene with excess diazomethane in the presence of copper compounds leads successively first to dicyclopropylcyclopropene resulting from multiple bond cyclopropanation and then to 1,3-dicyclopropylbicyclo[1.1.0]butane. The latter under the reaction conditions partially isomerizes to 2,3-dicyclopropylbuta-1,3-diene, which, in turn, undergoes further cyclopropanation. As a result, when an 8–10-fold excess of diazomethane is used, a hydrocarbon of the 1,1-oligocyclopropane series, 1,1′-dicyclopropylbicyclopropane (ivyane[4]), is formed. Monocyclopropanation of dicyclopropylbutadiene readily proceeds in the presence of Pd(acac)2, whereas cyclopropanation of the second double bond occurs only with a large excess of diazomethane.
