    • The invention relates to a method for producing acetylene alcohols of general formula (I), wherein R1, R2 can independently be identical or different and represent optionally substituted hydrogen, an optionally substituted saturated, monounsaturated or polyunsaturated C1-C30 alkyl radical, aryl radical, cycloalkylalkyl radical, or cycloalkyl radical, or a group of general formula (II), wherein R3, R4 can independently be identical or different and represent optionally substituted hydrogen or an optionally substituted saturated, monounsaturated, or polyunsaturated C1-C30 alkyl radical, aryl radical, cycloalkylalkyl radical, or cycloalkyl radical while the dashed line can represent an additional double bond. Said acetylene alcohols are produced by monoethynylating a ketone of general formula R1-CO-R2 by (a) reacting lithium with a C1-C10 alkyl halide, (b) introducing acetylene gas, and (c) adding the ketone.
    • 一种通过酮的单乙炔化生产乙炔醇的方法,包括:(a)锂与1-10C烷基卤的反应; (b)引入乙炔气; 和(c)加入酮。 通过式R1-CO-R2酮的单炔化反应制备式(I)炔炔醇的方法,包括:(a)锂与1-10C烷基卤的反应,(b)引入乙炔气和 (c)加入酮。 与C-CR1R2-OH(I)R1,R2 = H或任选不饱和的1-30C烷基,芳基,环烷基烷基或环烷基(全部被取代的)或式-CH2CH2CHR3R4或-CH2CH = CR3R4基团相当; 和R 3,R 4 = H或任选不饱和的,任选取代的1-30C烷基,芳基,环烷基烷基或环烷基。
