    • This invention pertains to a process for preparing diacetylenics, to diacetylenic compounds and to reduced diacetylenic compounds. The process includes the steps of reacting coupling an acetylenic acid in presence of cupric chloride in Ethylamine and hydroxylamine hydrochloride to form a diacetylenic diacid; reacting the diacetylenic diacid with a lithium compound, trimethylsilyl chloride and hydrochloric acid to form a diacetylenic compound; and reducing the diacetylenic compound to a reduced diacetylenic compound. The diacetylenic compounds have the formula COOH—(CH2)m—C≡C—C≡C—(CH2)m—C(═O)—R or R—C(═O)—(CH2)m—C≡C—C≡C—(CH2)m—C(═O)—R and the reduced cyclic diacetylenic compounds have the formula COOH—(CH2)m—C≡C—C≡C—(CH2)m—CH2—R or R—CH2—(CH2)m—C≡C—C≡C—(CH2)m—CH2—R, where m is 1-18 and R is selected from alkyl groups of 1-10 and cyclic groups containing 6-35 carbon atoms and aryl moieties
