|Title:||Studies on the synthesis of bis-quaternary ammonium salts of geometrical isomers and its potential as bioregulators|
Sharma, M L
Plant growth retardants
|Abstract:||Tertiary amine N,N-dimethyl-2-nitrophenylmethanamine 4 prepared from 2-nitrobenzaldehyde 3 by Leuckart’s reaction and (3-N,N-diethylamino-2-hydroxypropyl)-3-(3-nitrophenyl) prop-2-en-oate 9 and 3-(diethylamino)-2-hydroxypropyl 2-(4-chloro-3-methylphenoxy)acetate 14 prepared through the formation of glycidyl ester have been reacted with dichlorides of maleic acid and fumaric acid, which in turn have been prepared by reacting these acids with thionyl chloride to get bis-quaternary ammonium salts 1a-c and 2a-c. The synthesized salts 1a-c and 2a-c are tested on rice (Oryza sativa, PR-114) for their biological activity. All the tested compounds are found to possess good plant growth retardant activity. Compound 2c is found to be the best plant growth retardant among the six newly synthesized compounds.|
