this paper is concerned with 1-decyne which is a degradative product from the photooxidation of cyclopropenoid fatty acids (cpfa) naturally present in cottonseed oil. experiments were conducted to identify the factors involved in 1-decyne formation. reactions were done under the following conditions: (a) in the dark or under light, (b) with or without removal of cpfa from cottonseed oil, (c) in the presence of absence of singlet oxygen quenchers, (d) in the presence or absence of a hydroperoxide-reducing agent (triphenylphosphine), and (e) with or without photosensitizers. methyl sterculate was used as a substrate for studying 1-decyne formation under photosensitized oxidation conditions in a model system. it is concluded that 1-decyne is formed by the photooxidation of cpfa utilizing chlorophyll as a photosensitizer. a reaction mechanism for 1-decyne formation is proposed. 15 refs
