Di‐n‐butyltin and diethyltin monofluorobenzoates: Synthesis, spectroscopic characterization and in vitro antitumor activity

The di‐n‐butyltin(IV) and diethyltin(IV) fluorobenzoates [FC 6 H 4 COO] 2 SnR 2 and (FC 6 H 4 COOR 2 Sn) 2 O have been synthesized and characterized spectroscopically. Their in vitro antitumor activity against two human tumor cell lines, MCF‐7, a mammary tumor, and WiDr, a colon carcinoma, as well as against the NCI cell panel, is...
