Compounds of the formula ##STR1## wherein R.sub.1 and R.sub.2 are either two hydrogen atoms or together form a methylene group, and each X is a bromo, iodo or tosyloxy group and the dotted bonds indicate that the central linkage is attached to the two phenyl rings at positions which are either meta to both CH.sub.2 X groups or para to both such groups, possess anti-cancer activity. The active compounds are prepared by multi-step syntheses beginning with dimethoxymethylbenzaldehydes or di(hydroxymethyl)methoxyphenols; many of the intermediates involved are themselves novel.

hybrid cell line (D98/HR1) previously shown to induce carcinomas in nude mice. Inactivity of both test compounds in vitro, the relative resistance of these cells to test drugs in vitro, and the selective antitumor properties of the bis(bromomethyl) analogue in vivo lead to the proposal that this compound undergoes bioreduction to an alkylating species in the hypoxic core of the tumor, thereby exerting
