The present invention is directed to adamantane compounds of the formula: WHEREIN EACH G independently represents hydrogen or straight-chain alkyl of from one to six, both inclusive, carbon atoms; G' represents hydrogen or acetyl; R represents hydrogen or alkyl of from one to six, both inclusive, carbon atoms; R' represents halo, alkoxy containing from one to six both inclusive, carbon atoms in the alkyl group, hydrogen or alkyl of from one to six, both inclusive, carbon atoms; each R'' independently represents hydrogen or alkyl of from one to six, both inclusive, carbon atoms; each R''' independently represents hydrogen or alkyl of from one to six, both inclusive, carbon atoms or both R''' groups taken together represent oxo(-0); X represents halo; and each n independently represents an integer of from zero to one, both inclusive. The terms "halo" and "halide" are employed herein to designate occurrences of bromine, chlorine and iodine.
