ABSTRACT:
Described are p-methylenedioxyphenyl propionitrile and propiohydroxylamine derivatives defined according to the generic structure: ##STR1## wherein Z.sub.1 represents the moiety: ##STR2## and the moiety: ##STR3## and R.sub.1 is hydrogen or methyl and also having the generic structure: ##STR4## wherein X is HSO.sub.3.sup.- ; SO.sub.4 ;=Cl.sup.- ; PO.sub.4.sup..tbd. ; H.sub.2 PO.sub.4.sup.- ; and HPO.sub.4.sup.=. The p-methylenedioxyphenyl propionitrile and propiohydroxylamine derivatives having the structures: ##STR5## have useful organoleptic properties in the perfumery area. Also described are processes for preparing such p-methylenedioxyphenyl propionitrile and propiohydroxylamine derivatives. The compounds defined according to the structure: ##STR6## are useful intermediates in such processes. The subgenus defined according to the structure: ##STR7## covers novel compounds.
