✦ Synopsis

The following monocyclic and bicyclic 14-membered diynes all cases we obtained an intramolecular cyclobutadiene complex stabilized with a CpCo fragment (15-26). For 3 we were treated with [CpCo(cod)]: 1-oxacyclotetradeca-4,11diyne (2), 1,8-dioxacyclotetradeca-4,11-diyne (3), cyclotetra-could isolate, besides the cyclobutadiene complex 16, the trimerization product 28.

The reaction of cationic diolefinic rhodium(I) complexes with 2-(diphenylphosphino)benzaldehyde (pCHO) was studied. [Rh(cod) 2 ]ClO 4 (cod cycloocta-1,5-diene) reacted with pCHO to undergo the oxidative addition of one pCHO with (1,2,3-h)cyclooct-2-en-1-yl (h 3 -C 8 H 13 ) formation, and the coordin
