New compounds useful as intermediates for biologically-active compounds have the formula I ##STR1## wherein Y is a group having the formula --CH.sub.2 X in which X is F, Cl, or Br, or Y is a group having the formula ##STR2## in which R.sup.2 is F, Cl or Br and R.sup.3 is H, F, Cl, Br or a group having the formula --CR.sup.4 R.sup.5 R.sup.6, in which R.sup.4, R.sup.5 and R.sup.6, independently, are F, Cl or Br; A is H, OH, SH, F, Cl, Br or a group --OR.sup.7 or --SR.sup.7 in which R.sup.7 is C.sub.1 -C.sub.4 straight- or branched chain alkyl, C.sub.2-4 straight- or branched chain alkyl substituted with 1 to 3 F, Cl or Br atoms, or A is a group --NR.sup.8 R.sup.9 in which R.sup.8 and R.sup.9, independently, are H, C.sub.1 -C.sub.4 straight- or branched chain alkyl or C.sub.3 -C.sub.4 alkenyl, or R.sup.8 and R.sup.9 together may form a C.sub.3 -C.sub.7 polymethylene chain, which is optionally interrupted by an oxygen atom; as well as salts of compounds of formula I with acids; provided that: when Y is CH.sub.2 F, then A is as hereinbefore defined other than OH, Cl or OCH.sub.3.
