Ngaini Department of Chemistry, Faculty of Resource Science and Technology, Universiti Malaysia Sarawak, 94300 Kota Samarahan, Sarawak, Malaysia E-mail: [email protected] A series of mono- and hexa- substituted chlorocyclotriphosphazenes bearing 4 -[(4-alkoxy-benzylidene)amino]-phenol with different side chain has been synthesized. A convenient synthetic method was performed from the reaction of hexachlorocyclotriphosphazenes with one and six equivalents of 4 -[(4alkoxy-benzylidene)-amino]-phenol. The compounds differ in the length of alkyl groups, CnH2n+1, where n= 10, 12 and 14. The yield percentage for all the compounds is ranging from 30 to 40 %. The 1 13 31 spectroscopic techniques, FTIR, H NMR, C NMR, and P NMR, were employed to characterize the molecular structure. 193 23rd-25th June 2010 3rd ICYC 2010 Universiti Sains Malaysia ORG-O18 SYNTHESIS AND STRUCTURAL STUDIES OF METHYL- AND ETHYL-2-(3-CINNAMOYLTHIOUREIDO) ACETATE FROM 2-(3-CINNAMOTHIOUREIDO) ACETIC ACID Ibrahim N. Hassan, Bohari M. Yamin and Mohammad Kassim School of Chemical Sciences & Food Technology, Faculty of Science & Technology, Universiti Kebangsaan Malaysia, 43600 Bangi, Selangor, Malaysia E-mail: [email protected] Two new cinnamoylthiourea derivatives of glycine namely methyl -2-(3-cinnamoylthioureido)acetate (MCT) and ethyl-2-(3-cinnamoylthioureido)acetate (ECT) have been successfully synthesized. The new compounds were obtained through esterification of the carboxylic acid derivatives by aqueous namely methanol and ethanol in the presence of LaCl3. The new compounds were characterized...
