Project 1: Organometallic Reagents in Organic Synthesis

The oxidative-addition reaction between an arylmethyl chloride (RCH2Cl;R=1-C10H7, 2,4,6-Me3C6H2, 4-MeC6H4, 3-MeC6H4, C6H5, 4-ClC6H4) and tin powder in boiling toluene produces bis(arylmethyl)tin dichlorides, [(RCH2)2SnCl2] in good yields. At 160°C in mesitylene bis(1-naphthylmeth-yl)tindichloride undergoes Sn-C homolytic cleavage to generate two 1-naphthylmethyl radicals (1-C10H7CH2·) which were trapped by TEMPO (C9H8NO·). Subsequently, the radicals (RCH2·) produced in this manner were utilized for efficient substitution reactions with electron-rich arenes (R’H; R’=2,4,6-Me3C6H2, 1,2,4,5-Me4C6H,1,2,3,4,5-Me5C6) to obtain a variety of unsymmetrical diarylmethanes (RR’CH2). The addition of one equivalent of iodine (I2) to the reaction mixture resulted in a significant increase in the yields of coupled products.

Project 2: Inorganic Materials For Magnetic Applications

We report the structural and magnetic properties of nanocrystalline Sn0.5Fe0.5O2−δ prepared by thermal decomposition of hexameric organotin ferrocenecarboxylate. The X-ray diffraction study revealed that Fe doping retains the tetragonal rutile structure of SnO2. FTIR shows the presence of O–Sn–O stretching vibration. Microstructural investigation by FESEM and HRTEM indicated nanoparticle agglomeration and different orientations of lattice fringes with an interplanar spacing of 0.332 nm. The XPS analysis unveiled the incorporation of Fe3+ ions into the SnO2 matrix. Mössbauer spectroscopy suggested the presence of Fe3+ ions in a distorted octahedral environment. Bulk magnetization and ac susceptibility studies assert the presence of competing ferromagnetic and antiferromagnetic interactions and a cluster spin glass state (Tg = 72 K) at low temperatures.
