, p. 301 - 304 (2014/06/24)
The grinding-induced reactions of 2-aminobenzyl alcohol and benzaldehyde derivatives in the presence of 30 mol% of acetic acid to give 3,1-benzoxazines are described. The reactions were performed at room temperature affording 3,1-benzoxazines in yields above 95% and high purity when benzaldehyde and its chloro and nitro derivatives were used.

A few new dimetallic manganese(II) complexes of the type 2 (where AAAH2 = schiff base derived from salicylaldehyde, 5-nitrosalicylaldehyde, 5-chlorosalicylaldehyde, 5-bromosalicylaldehyde, 3,5-dichlorosalicylaldehyde or 2-hydroxy-1-naphthaldehyde and ortho-aminobenzyl alcohol) have been synthesized and characterized on the basis of elemental analysis, molecular weight, electrical conductance, infrared spectra and magnetic susceptibility measurements.The schiff bases act as ONO donor dibasic tridentate ligands.A dimetallic six-coordinated and octahedral μ-bis(schiff base) tetraaquodimanganese (II) structure is suggested for the complexes.

New Oxozirconium(IV) Complexes with the Schiff Bases Derived from Salicylaldehyde or Substituted Salicylaldehydes and o-Aminobenzyl Alcohol

, p. 1018 - 1020 (2007/10/02)
Several new oxozirconium(IV) complexes with the schiff bases obtained from salicylaldehyde, 5-chlorosalicylaldehyde, 5-bromosalicylaldehyde, 5-nitrosalicylaldehyde, 4-methoxysalicylaldehyde, 5-methoxysalicylaldehyde, 3-ethoxysalicylaldehyde, 3,5-dichlorosalicylaldehyde or 2-hydroxy-1-naphthaldehyde and o-aminobenzyl alcohol have been synthesized and characterised on the basis of elemental analysis, molecular weight, electrical conductance, infrared spectral and magnetic susceptibility measurements.The schiff bases behave as monobasic, tridentate ONO donor ligands.The complexes are of the type ZrO(LH)2 (where LH2 = tridentate schiff base) and are seven-coordinated.The complexes are monomers, non-electrolytes and diamagnetic.Changes in the νC=N, νC-O (phenolic) and νC-O (alcoholic) frequencies have been followed to find out the coordination sites of the ligands.
New Iron(III) Complexes of Tridentate ONO Donor Dibasic Schiff Bases Derived from Salicylaldehyde or Substituted Salicyaldehydes and o-Aminobenzyl Alcohol
Syamal, A.,Kale, K. S.
, p. 488 - 491 (2007/10/02)
The synthesis of several new iron(III) complexes of the schiff bases derived from salicylaldehyde, 5-bromosalicylaldehyde, 4-methoxysalicylaldehyde, 3-ethoxysalicylaldehyde, 3,5-dichlorosalicylaldehyde, 2-hydroxy-1-naphthaldehyde and o-aminobenzyl alcohol are described.The schiff bases coordinate through O (phenolic), N (azomethine) and O (alcoholic) atoms as dibasic tridentate ligands.The complexes are characterized on the basis of elemental analysis, magnetic susceptibility, infrared spectra, molecular weight and conductance measurements.The complexes are of the type FeCl(L) where LH2 = tridentate dibasic schiff bases.The complexes are non-electrolytes, dimeric in nature and exhibit effective magnetic moments in the range 4.37-4.55 B.M.The dimeric nature and the low effective magnetic moments are indicative of antiferromagnetic exchange in these complexes.A dimeric structure with alcoholic oxygen atoms as the bridging atoms is proposed for these complexes.The complexes are five-coordinated and square-pyramidal with Fe-O-Fe bridge.
Magnetic Properties of New Oxovanadium(IV) Complexes of Tridentate Dibasic Schiff Bases Derived from Salicylaldehyde or Substituted Salicylaldehyde and o-Aminobenzyl alcohol

, p. 225 - 228 (2007/10/02)
Some new oxovanadium(IV) complexes of the schiff bases derivad from salicylaldehyde, 5-chlorosalicylaldehyde, 5-bromosalicylaldehyde, 3-methoxysalicylaldehyde, 3-ethoxysalicylaldehyde and o-aminobenzyl alcohol have been prepared and characterized on the basis of elemental analysis, electronic and infrared spectra, and magnetic susceptibility measuerments (83-294 K).The complexes exhibit subnormal magnetic moments (μeff = 1.18-1.57 B.M. at room temperature).The effective magnetic moments of the complexes decrease significantly as the temperature is lowered indicating the presence of antiferromagnetic exchange with S = 0 as the ground state.The exchange integral (J) of the complexes is in the range 121-245 cm-1.The complexes exhibit the ν V=O frequency in the region 910-985 cm-1.The complexes show three electronic spectral bands around 13000, 18000 and 22000 cm-1 due to the transitions dxy --> dxz, dyz; dxy --> dxz-yz; and dxy --> dz2 respectively.On the basis of infrared spectra and magnetic susceptibility data a dimeric structure with aminobenzylalcoholic oxygen atoms as the bridging atoms, is suggested.
