2-Methylbut-3-yn-2-ol also is used as a monoprotected version of acetylene. For example, after arylation at carbon, the acetone can be removed with base: Buy 3-Butyn-1-ol solution (CAS 927-74-2)
HC2C(OH)Me2 + ArX + base → ArC2C(OH)Me2 + [Hbase]X
ArC2C(OH)Me2 → ArC2H + OCMe2
In this regard, 2-methylbut-3-yn-2-ol is used similarly to trimethylsilylacetylene.

GENERAL DESCRIPTION & EXTERNAL LINKS Alkynyl substrate used in a study of a palladium-catalyzed coupling with -tetrionic acid bromide leading to alkynyl substituted furanones in good yield. Synthon for preparation of oxygen-containing heterocycles and protected esters of s-Hydroxy-L-isoleucine. Acetylenic alcohol containing -OH and triple bond can be applicable to; Corrosion inhibitor formulation Metal complex solution Solvent stabilizer Biodegradable chemical intermediate to make pesticides, biocides and pharmaceuticals. Acetylene chemistry and reagents Alkynes contain a highly versatile functional group that may be utilized for numerous reactions such as electrophilic additions of hydrogen, halogens, hydrogen halides, or water; metathesis; hydroboration; oxidative cleavage; C-C coupling; and cycloadditions. Terminal alkynes may be transformed into metal acetylides and can then be submitted to nucleophilic substitution with alkyl halides, forming new C-C bonds, or nucleophilic addition, e.g., the Favorskii reaction.

The general structure of the alkyne hydrocarbons with one triple bond is CnH2n-2. They are insoluble in water but easily soluble in common organic solvents of low polarity. The features of alkynes in chemical synthesis is due to the acidity of hydrogen atoms bonded to triply bonded carbons as well as the triple bonds themselves. Addition reactions are typical in alkyne reactions; halogenation, hydrogenation, hydrohalogenation, hydration, oxidative cleavage, nitrile formation and acidity of terminal alkynes. Polymerisation and substitution reactions are also useful in chemical synthesis. Addition Reactions Catalytic Hydrogenation by Pt and Pd hydrogenation catalysts to yeild alkanes without isolation of alkene intermediates. Catalytic Hydrogenation by Lindlar’s catalyst to yeild cis- or trans- alkenes without further reduction to alkanes Addition by Electrophilic Reagents Addition of halides (chlorine, bromine, iodine) to yield dihalogen substituted alkanes at the solid bond site Addition of hydrogen halides (HCl, HBr, HI) to yield monohalogen substituted alkenes or dihalogen substituted alkanes Hydration of alkynes to yield ketone products through enol tautomer intermediate stage, whereas the hydration of solid bonds gives alcohol products (exceptionally acetylene yields acetaldehyde ). Hydroboration by disiamylborane to yield ketones or aldehydes Oxidation cleavages of the triple-bond to give carboxylic acid products with oxidizing agents (potassium permanganate and ozone) Nucleophilile Addition by sp-hybrid carbon atoms of the triple-bond render alkynes (nitrile formation) Nucleophilile Reduction by solutions of sodium in liquid ammonia to trans-alkenes The name of all alkynes end in “-yne” adding a prefix to indicate the location of the triple bond in the molecule.
