Cyclopropanation of 1-methylidene-2-phenylcyclopropane with dimethyl diazomalonate affords new dimethyl 4-phenyl-spiro[2.2]pentane-1,1-dicarboxylate. On contact with EtAlCl2, this compound undergoes opening of both cyclopropane rings to give dimethyl (2-chloromethyl-3-phenylallyl)malonate. Its EtAlCl2-assisted reaction with methyl 5′-methylspiro[cyclo-propane-1,3′-pyrazoline]-5′-carboxylate proceeds as the 1,3:1′,5′-addition to afford mainly 3-(2-chloroethyl)-1-cyclo-propylmethyl-1H-pyrazoline derivative.
Pd-catalyzed ring-opening copolymerization of 2-aryl-1-methylenecyclopropanes with CO to afford polyketones via alternating insertion of the two monomers and C - C bond activation of the three-membered ring
