The reaction of propargylic alcs. HCCC(OH)R1R2 [R1 = Me, R2 = Me, Et, Me2CHCH2; R1 = R2 = Et; R1R2 = (CH2)5] with carboxylic acids R3CO2H (R3 = Me, MeOCH2, H2C:CMe, Me3C, Ph, etc.) or phenols R4OH (R4 = 2-ClC6H4, 4-O2NC6H4, 4-MeC6H4, etc.) in the presence of the precatalyst [RuCl(cod)(C5Me5)] leads selectively to a variety of alkylidenecyclobutenes I (R5 = R3CO or R4) through head-to-head dimerization of propargylic alc. The first step is the formation of a cyclobutadiene-ruthenium intermediate resulting from the head-to-head coupling of two mols. of propargylic alc. On protonation with strong acids (HPF6, HBF4), dehydration of this cyclobutadiene complex takes place leading to formation of an alkylidenecyclobutenyl-ruthenium complex. The X-ray structure of one such complex, [RuCl(C5Me5)(η4-R6CCH-CH-C=CR72)] [R6 = cyclohexen-1-yl; R72 = (CH2)5] has been determined Carboxylate is added at the less substituted carbon of the cyclic allylic ligand. DFT/B3LYP calculations confirm that the intermediate arising from head-to-head coupling of alkyne to the RuClCp* species yields the cyclobutadiene-ruthenium complex more easily with propargylic alc. than with acetylene.
