Descrição geral

Methyl 2-octynoate has been quantitated as suspected allergen in cosmetic products by headspace-programmed temperature vaporization-fast gas chromatography-quadrupole mass spectrometry. It participates in nickel-catalyzed carbocyclization of 2-iodoacetophenone to yield a 2,3-disubstituted indenol.
