A series of organotin(IV) carboxylate complexes [Me2SnL 2] (1), [Bu2SnL2] (2), [Oct2SnL 2] (3), [Me3SnL] (4), [Bu3SnL] (5) and [Ph 3SnL] (6), where L = O2C(CH3)CCHC 6H4F have been successfully synthesized and characterized by FT-IR, NMR (1H, 13C) and single crystal analysis. The ligand coordinates to tin atom via carboxylate group. Compound 1 and 4 have also been studied by single crystal XRD analysis. The synthesized compounds were screened for their biological activities including anti-bacterial, anti-fungal, anti-tumor and cytotoxicity. The compounds 4-6 exhibit excellent anti-bacterial, anti-fungal and anti-tumor activities. The ligand binds with DNA double helix by hydrogen bonding between the ligand and the base pairs in DNA typically to N3 of adenine and O2 of thymine as well as partial intercalation of aromatic ring into the base pairs of DNA. The complexes also interact with DNA via intercalation of aromatic ring into the base pairs of DNA. The catalytic activity of compounds 46 was assessed in transesterification of triglycerides in rocket seed oil into biodiesel. The choice of these compounds is the Lewis acid nature of tin atom. The samples were taken in regular interval of 1, 8, 16 and 24 h and % age conversion was determined by 1H NMR. All the tested compounds showed good catalytic activity in the order 4 > 5 > 6.

The contra-thermodynamic isomerization of α- and β-substituted cinnamate derivatives catalyzed by the Cu(OAc)2/rac-BINAP complex under blue light irradiation is reported. The use of an oxazolidinone template, which favored the complexation of the copper catalyst to the substrate, allowed the E → Z isomerization of the catalytically formed chromophore under simple and robust reaction conditions in good to excellent ratios. The mechanism of this process based on the transient formation of a chromophore was also studied.
Pd-Catalyzed α-Selective C-H Functionalization of Olefins: En Route to 4-Imino-β-Lactams

Pd-catalyzed α-olefinic C-H activation of simple α,β-unsaturated olefins has been developed. 4-imino-β-lactam derivatives were readily synthesized via activation of α-olefinic C-H bonds with excellent cis stereoselectivity. A wide range of heterocycles at the β-position are compatible with this reaction. The product of 4-imino-β-lactam derivatives can be readily converted to 2-aminoquinoline which exists extensively in pharmaceutical drugs and natural products.
