Four distinct organotin(IV) compounds, [R 2 Sn-(L 1 )] [R = Ph (1) and n-Bu (2)] and [R 2 Sn(L 2 )] [R = Ph (3) and n-Bu (4)], have been synthesized from two polydentate proligands such as 2-((2-hydroxy-3-methoxybenzylidene)amino)-4-methyl phenol (H 2 L 1 ) and 4-(tert-butyl)-2-(((2-hydroxy-5-methylphenyl)imino)methyl)phenol (H 2 L 2 ). The organotin(IV) compounds were synthesized by the reaction of organotin(IV) halides such as Ph 2 SnCl 2 and (n-Bu) 2 SnCl 2 with both proligands using Et 3 N as a base. All compounds were fully characterized using FT-IR spectroscopy; 1 H, 13 C{ 1 H}, and 119 Sn NMR spectroscopy; HRMS spectrometry; and single-crystal X-ray diffraction analysis. The Lewis acidity of all compounds was determined by the Gutmann− Beckett method. The catalytic activities of all of the compounds were investigated for the synthesis of naphthofurans from trans-β-nitrostyrene derivatives and β-naphthol or α-naphthol under solvent-free conditions. The maximum yield of naphthofurans is up to 95%.
