Di-n-butyltin oxide reacted with p-[N,N-bis（2-chloroethyl）amino]benzoic acid to yield the compounds {{4-[（ClCH2CH2）2N]C6H4COOSnBu2}2O}2 （1） and {4-[（ClCH2CH2）2N]C6H4COO}2SnBu2 （2）, which have been characteri...Di-n-butyltin oxide reacted with p-[N,N-bis（2-chloroethyl）amino]benzoic acid to yield the compounds {{4-[（ClCH2CH2）2N]C6H4COOSnBu2}2O}2 （1） and {4-[（ClCH2CH2）2N]C6H4COO}2SnBu2 （2）, which have been characterized by IR and ^1H NMR spectra. The X-ray diffractional studies of 1 reveal the structure of the molecule to be a dimer, in which the two Bu2Sn groups were linked via two bridging oxygen atoms to form a central Bu4Sn2O2 unit. And the tin atom adopts two carbons from two n-butyl groups and three oxygen atoms from the acid and the bridging oxygen. In vitro test showed compound 1 to exhibit high cytotoxicity against P388 and HL-60 cell lines.展开更多
