Srivastava, Manish Kumar’s team published research in Main Group Metal Chemistry in 37 | CAS: 4551-69-3

Srivastava, Manish Kumar published the artcileCoordination propensity of N-protected amino acids and sterically congested heterocyclic 尾-diketones toward BuSnCl₃: preparation and structural features of some new seven coordinated organic-inorganic hybrid formulations of monobutyltin(IV), COA of Formula: C17H14N2O2, the publication is Main Group Metal Chemistry (2014), 37(3-4), 75-83, database is CAplus.

Organotin carboxylate complexes I (1–4; 1, X = CH₂CH, R = H, R¹ = Ph; 2, X = CH₂CH, R = H, R¹ = Me; 3, X = CH, R = s-Bu, R¹ = Ph; 4, X = CH, R = s-Bu, R¹ = 4-ClC₆H₄) and II (5–8; 5, X = CH₂CH, R = H, R¹ = P h; 6, X = CH, R = s-Bu, R¹ = Ph; 7, X = CH, R = s-Bu, R¹ = 4-ClC₆H₄; 8, X = CH, R = s-Bu, R¹ = Me), derived from phthaloyl-protected amino acids, were prepared by the reactions of monobutyltin(IV) chloride with sodium salts of N-protected amino acids and sterically congested heterocyclic 尾-diketones in 1:1:1 and 1:2:1 molar ratios in refluxing dry THF and characterized by spectral methods. Plausible structures of these N-protected amino acids and sterically congested heterocyclic 尾-diketones-modified BuSnCl₃ formulations were suggested on the basis of physicochem. and spectral studies. These newly prepared organic-inorganic hybrid complexes of monobutyltin(IV) contain seven coordinated tin centers as revealed by ¹¹⁹Sn NMR spectral data.
