C6 acetylenic alcohols are important intermediates in the synthesis of Vitamin A and carotenoids. New synthesis methods of the C6 acetylenic alcohols and their four derivatives are reported. These designed synthesis methods are useful improvement to the present methodologies. Structures of these compounds are confirmed by 1H NMR, IR and mass spectra analysis.

An acetylene alcohol represented by the following formula,
wherein R
1
represents a monovalent hydrocarbon radical having 4 to 10 carbon atoms with the carbon atom bonded to the silicon atom being a tertiary carbon,
R
2
and R
3
each represents a monovalent group selected from the group consisting of alkyl groups having 1 to 4 carbon atoms and a fluorinated group represented by the formula, Rf-Q-, wherein Rf is a linear or branched perfluoroalkyl group having 3 to 100 carbon atoms which may be interrupted by one or more ether bonds, and Q is a divalent group having 2 to 10 carbon atoms which may be interrupted by one or more nitrogen, oxygen, or sulfur atoms, and n is zero or 1.
