    • Indeed, the formation of the corresponding allenylidene intermediate was confirmed in the reaction. The reason for the lack of reactivity is not clear, but we consider that the more electron-rich p-tolyl moiety contributes to the increased stability of the allenylidene intermediate, which inhibits the nucleophilic attack of EtOH to the allenylidene moiety

    • The stoichiometric reaction of 7 with EtOH in the presence of an excess amount of 1,1-bis(4-methylphenyl)-2-propyn-1-ol was investigated,5,12 but no formation of 5 was observed at all, while the formation of oligomers of 5 was confirmed by 1H NMR. This result indicates that 5 was at first formed and further reaction of 5 took place to form the corresponding oligomers of 5
