General Base Catalyzed Hydrogen Exchange of 1-Octyne, 4-Nitrophenylacetylene, and 3-(Phenyldimethylammonio)-1-propyne. Broensted Relations and Normal Acid Behavior
Kresge, A. J.,Powell, M. F.
, p. 822 - 824 (1986)
Rates of loss of tritium from the title compounds labeled at the acetylenic hydrogen position were measured in aqueous primary amine buffer solutions at 25 deg C.These data give Broensted relations with essentially unit exponents: β = 0.97 +/- 0.06 for 1-octyne, β = 0.97 +/- 0.05 for 4-nitrophenylacetylene, and β = 0.98 +/- 0.05 for 3-(phenyldimethylammonio)-1-propyne, which indicates that these acetylenes are "normal" rather than pseudo carbon acids.

A monosubstituted ionic polyacetylene having a quaternary ammonium salt was synthesized and characterized. The polymerization of dimethylphenylpropargylammonium bromide (DMPPAB) was performed by various transition metal catalysts to give the resulting pol

Quaternization of N,N-dimethylaniline with propargyl bromide, 1-bromobut-2-yne, and 1-bromooct-2-yne were studied. It was shown that, with the lengthening chain of the substituent at the triple bond, the quaternization rate tends to increase.
