Poly(propargyl pyridinium bromide), a kind of conjugated polyelectrolyte with polyacetylene as the backbone and pyridinium as side groups, was synthesized simply via reaction between pyridine and propargyl bromide under mild conditions. The resultant polymer was characterized by (1)H NMR, elemental analysis, FT-IR, and GPC-MALLS. An alkyne group was confirmed as the end group of the polymer cha...

The present work describes, the reaction between disodium salt of 1,3-dihydroxybenzene (in situ formation) and propargyl bromide was carried out in a solid-liquid biphasic phase transfer catalytic system at 50°C. Higher selectivity of the bis-derivative (1,3-bis(prop-2-ynyloxy)benzene) was obtained under solid-liquid PTC condion. The conversion of propargyl bromide of more than 99% was achieved...

Rearrangement of propargyl amine salt, in the presence of a base was studied and it was concluded that this occurs through an allenic intermediate.

Condensation and cyclization of 5-hydroxy- 1,2,4- thiadiazol-2-yl hydrazine 1 with pyruvic acid, phenacyl bromide, propargyl bromide and ally1 bromide afforded compounds 2,5,7 3, 4 ,6 and 8 respectively, Reaction of 1 with epichforohydrine afforded 4-hydroxy-N-[5-hydroxy- 1 ,3,4-thiadiazoly1] pyrazolidine 9

A series of aminoacetylenicoxyphthalimide namely N-[4-(t-amino)-2-butynyloxy] phthalimides were synthesized from the reaction of N-hydroxyphthalimide with propargyl bromide in sodium ethoxide to generate N-(2-butynyloxy)phthalimide. The desired compounds were prepared through Mannich reaction of N-(2-butynyloxy)phthalimide with formaldehyde, appropriate amine in peroxide-free dioxin and cuprous...

Propargyl bromide is being investigated for its potential as a soil fumigant. Characterization of the fate of propargyl bromide in soil is important in determining both efficacy and the threat of environmental contamination. These experiments investigated some of the factors affecting the rate of propargyl bromide degradation in soil and quantified some of the products formed as a result of pro...
