Copper catalyzed regioselective coupling of allylic halides and alkynes promoted by weak inorganic bases

Allylic halides and terminal alkynes couple under CuI catalysis in DMSO or DMF solution. In most cases, sodium carbonate or bicarbonate is sufficient to promote the reaction; less reactive alkynes require catalytic amounts of DBU. Bifunctional alkynes and halides can be reacted selectively according to the stoichiometry used. Trimethylsilyl, hydroxyl, ester and halide groups are tolerated in the alkyne. Most halides react without allylic rearrangement. The method is suitable for the synthesis of functionalized enynes.

Allylacetylenes and their derivatives as inhibitors of steel corrosion in sulfuric acid

New functionalized derivatives of allylacetylenes were prepared, and their ability to inhibit corrosion of St.3 low-carbon steel in 5 N sulfuric acid was studied. The effectiveness of inhibition of steel corrosion was studied in relation to the structure of acetylene derivatives, their concentration, and temperature of acidic medium.

Reactions of Monosubstituted Acetylenic Alcohols with Allyl Halides

Reactions of 2-propynyl alcohol and 2-methyl-3-butyn-2-ol with mono- and dihalogenated propenes yield allylacetylenic alcohols.The kinetic study showed that the reaction rate is governed by both electronic and steric effects of substituents in the allyl halides.

Method of preparing C-18 ketones used in the manufacture of Vitamins E and K

Methods of forming unsaturated C-18 ketones which can be used in the synthesis of Vitamins E and K1 are disclosed. One procedure involves coupling a C-9 primary allylic halide to a carbonyl-group-containing C-9 terminal alkyne. A second, two-step procedure employs a C-4 bis allylic halide (molar excess) and a carbonyl-group-containing C-9 terminal alkyne to form a C-13 primary allylic halide. The C-13 primary allylic halide can then be converted to the desired C-18 ketone by reaction with 2-methyl-3-butyn-2-ol. Novel C-18 ketones (e.g., 14-hydroxy-6,14-dimethyl-10-methylene-5-pentadecen-7,12-diyn-2-one), C-13 allylic halides (e.g., 10-chloromethyl-6-methyl-5,10-undecadien-7-yn-2-one) and C-9 allylic halides (e.g., 6-chloromethyl-2-methyl-6-hepten-3-yn-2-ol) are formed in the process.
