Efficient Synthesis of Five Types of Heterocyclic Compounds via Intramolecular Elimination Using Ultrasound-Static Heating Technique

An experimental technique, ultrasound-static heating, has been developed for the efficient synthesis of heterocyclic compounds. The technique involves ultrasonic irradiation and static heating processes. First, the ultrasonic irradiation process is performed to form an intermediate of the heterocyclic compound under mild conditions and the subsequent static heating process (heating the intermediate under solvent-free conditions without stirring) produces the target heterocyclic compounds via intramolecular elimination.

Process for the manufacture of pyrazolones from pyrazolidones

A process for manufacture of pyrazolones of the formula: STR1 wherein R is an aromatic radical and R1 is an alkyl, carboxylic acid, carbamoyl or carboxylic ester group which comprises treating a pyrazolidone of the formula: STR2 wherein R and R
