Theoretical Studies on the Intramolecular Cyclization of (Z)-8-(Trimethylstannyl)oct-6-enal;

Cyclization in situ of Isoprene Polymerization Catalyzed by Nd-Al Bimetallic Complex;

Synthesis of 3 Acylhydrazino 5 (2,4 dichlorophenyl) 1,3,4 oxadiazole and Studies on Their Cyclization;

In this paper,the title compound was synthesized through cyclization reaction of p-methylbenzoic acid,p-chloromethylbenzoic acid and p-nitrilbenzyl chloride with 4,6-diaminoresorcinol dihydrochloride.

The intermediate of Tinoxicam,4-hydroxy-3-methyl-2H-thieno-1,2-thiazine-2-(methyl) carboxylate-1,1-dioxide(MHTTCD) was synthesized from methyl 3-amino-2-thiophene methyl carboxylate through four steps: chlorosulfonylation,methylamination,N-alkylation,and cyclization.

The synthesis of furan phenol through cyclization were studied, catalyzed by aluminium alkoxide and the affect of the catalyst weight against the selection of furan phenol and the feeding in or distilling out of the alcohol against the reaction yield of product.

The cyclic reaction characters of CaCO3 and three dolomites with CO2 was experimentally investigated.

The cyclic reaction characteristic of CaO/Ca12Al14O33, limestone and dolomite with CO2 were investigated by using TGA.

Then 4-oxy-7-methyl-1,8-naphththyridine-3-carboxylic acetate was synthesized by cyclization reaction in different heat carr.

Potassium maleate-containing ionomers were prepared by ring-opening reaction of epoxidized styrene-butadiene-styrene block copolymer(SBS).

Epoxidized styrene-butadiene-styrene triblock copolymer(ESBS) can react with potassium hydrogen maleate by ring-opening reaction in the presence of phase transfer catalyst and ring-opening catalyst.

Sodium sulfonated SBS ionomer was made from epoxidized styrene-butadienestyrene triblock copolymer(ESBS) and NaHSO_3 by ring-opening reaction in the presence of phase transfer catalyst,ring-opening catalyst and pH value regulator.
