Insecticidal N-(arylalkyl)-4-[Bis(substituted aryl)hydroxymethyl]azabicyclo[3.3.1.]nonanes and [3.2.1.]octanes

A compound of the formula:

• ##STR11## in which m is 2 or 3;
• n is 0 or 1;
• W is hydrogen or alkoxy;
• X is hydrogen, alkoxy, cycloalkylalkoxy, alkoxycarbonyl, alkoxycarbonylamino, alkoxyimino, haloalkoxyimino, or a five-or six-membered heteroaryl or heteroaryloxy in which one or more hetero atoms may be optionally substituted with an alkyl;
• R.sup.1 and R.sup.2 are independently selected from hydrogen, haloalkyl, halothio, or haloalkoxy;
• and
• when n is 1, Y represents (a) an N-oxide of the ring nitrogen or (b) an agriculturally acceptable anionic salt of the ring nitrogen;
• or (c) forms an OR.sup.3 linkage in which R.sup.3 is selected from hydrogen, alkyl, alkoxycarbonylalkyl, hydroxycarbonylethyl, in association with an agriculturally acceptable anion resulting in an anionic salt, or R.sup.3 is an oxycarbonylalkyl group bearing a negative charge resulting in an inner salt.
