Name: SAAD EL ADAWEY SHEHATA HAMOUDA Title of Thesis :
”Using 2- heterylacetonitrile Compounds in Synthesis of Some New Derivatives with Anticipated Pes~icidal Efficiency”
Degree :Ph.D. Thesis Faculty of Science Helwan Unversity.
This work has been carried out to investigate a novel synthesis of u-
(benzoxazole-2-yl)-~-
benzoxazole-2,4-dicarbonitrile, pyrido . carbonitrile-2-ethyl(lH) (thio) nes,
crotonitrile, pyrido[2, I-b]
[2, I-b ] benzoxazole-4-
u- (benzoxazole-2-yl)-~-
strenylcrotonitrile, u- (benzoxazole-2-yl)-~- cycloalkylidene crotonitrile,
5-aryl-6-cyano- 3 - methyl- 2-(benzoxazole- 2- yl) ethoxycarbonyl- 3- methyl- 2-(benzoxazole- 2- yl)
6-( thio )amide- 2-(benzoxazole- 2- yl) aniline,
aniline, 5-aryl-3-methyl¬3.,(benzoxazole- 2- yl)- 2-
mercapto-4-methyl-6-pyridinethione. The newly synthesized compounds were tested biologically against wheat and cucumber as patterns for monocotyledonous plants and dicotyledonous plants, which were taken as indicators for the herbicidal efficiency of these compounds.
