A compound of the formula:
- ##STR3## wherein:
- n is 1 or 2;
- X is chlorine or fluorine;
- R is alkyl;
- R.sub.1 and R.sub.2 are individually alkyl or haloalkyl or R.sub.1 and R.sub.2 together may form an alkylene chain completing either a substituted or unsubstituted cyclopentyl, cyclohexyl or either a 6, 7 or 8 membered bicycloalkyl ring wherein the permissible substituents are one or more chloro, fluoro, bromo, alkyl or haloalkyl substituents;
- with the proviso that R, R.sub.1, and R.sub.2 substituents individually may not include more than eight aliphatic carbon atoms.
