Synthesis and Characterization of Schiff Base Derivatives of Organoheterobimetallic dibutyl [Sn(IV); B(III)]-µ-oxoisopropoxide | Chapter 12 | Advancements in Science and Technology: Paving the Way to a Sustainable Future

A number of reactions of organoheterobimetallic dibutyl[Sn(IV); B(III)] μ-oxoisopropoxide with bidentate Schiff bases (HSB) i.e Salicylidene aniline (HSB¹), Salicylidene-o-toluidene (HSB²) and Salicylidene-p-chloroaniline (HSB³) are performed in different molar ratios (1:1-1:2) in refluxing benzene results in the formation of products of the type [Bu₂SnO₂B₂(O-i-Pr)_4-n(SB)_n] (where n = 1-2 ). The isopropanol liberated during the course of reaction is collected azeotropically (isopropanol-benzene) and estimated oxidimetrically to check the progress of the reaction. The derivatives have been characterized by elemental, liberated isopropanol and spectral analysis (IR, ¹H, ¹³C,¹¹⁹Sn and ¹¹B NMR). All the Schiff base derivatives are found to be brownish yellow highly viscous liquid to gel type, soluble in organic solvents and susceptible to hydrolysis.
