Antioxidative vs cytotoxic activities of organotin complexes bearing 2,6‐di‐tert‐butylphenol moieties

Two series of organotin(IV) complexes with Sn–S bonds on the base of 2,6‐di‐ tert ‐butyl‐4‐mercaptophenol ( L 1 SH ) of formulae Me 2 Sn(L 1 S) 2 ( 1 ); Et 2 Sn(L 1 S) 2 ( 2 ); Bu 2 Sn(L 1 S) 2 ( 3 ); Ph 2 Sn(L 1 S) 2 ( 4 ); (L 1 ) 2 Sn(L 1 S) 2 ( 5 ); Me 3 Sn(L 1 S) ( 6 ); Ph 3 Sn(L 1 S) ( 7 ) (L 1 = 3,5‐di‐ tert ‐butyl‐4‐hydroxyphenyl), together with the new ones [Me 3 SnCl(L 2 )] ( 8 ), [Me 2 SnCl 2 (L 2 ) 2 ] ( 9 ) ( L 2 = 2‐(N‐3 ′ ,5 ′ ‐di‐...
