Abstract
The yields of CpCo-capped cyclobutadiene superphane from 1,6-cyclodeca diyne (1) and (R-C5H4)Co(cod) varies considerably with the substituent s R. Electron-withdrawing substituents give yields between 35 and 45 % while electron-donating substituents give very small yields. In the c ase of 1,8-cyclotetradecadiyne (2) such a dependence on R is much less pronounced. The reaction between 1 and 2 and the indenyl complex (eta 5-C9H7)Co(cod) is also reported.
