STUDIES ON ORGANOMETALLIC CHEMISTRY OF RUTHENIUM

Abstract

Reaction of pthaladehyde with primary amine in ethanol gave rise to isoindole derivative. Two derivatives namely 4-methyl-N-(2-p-tolylisoindolin-l-ylidene)benzenamine (Li) and 4-methoxy-N-(2-(4-methoxyphenybisoindolin-l-ylidene)benzenamine (L2) were structurally characterized X-ray diffraction and by elemental analysis, UV-VIS and IR studies. Crystal data of LI are as follows: crystal system, orthorhombic; space group Pna21; a=19.0212A, b=12.7684A, c=7.1666 A, ar-p=y=90°, V= 1740.6A3; Z=4; RI=10.6%; wR2=15.98%. Crystal data of L2 are as follows: crystal system, monoclinic; space group P-I; a--=5.1956 A, b=13.1475 A, c=13.4222 A, a=107.855°, (3=98.780°, y=95.820°; V=916.859 A3; Z=2; R1=6.79%; wR2=29.97%. LI and L2 result an orthometallated ruthenium complex when they react with Ru(PPh3)3C12. The resultant organometallic ruthenium complexes were characterized by elemental analysis, UV-VIS, IR and IH NMR studies.
