Although the major product from solvolysis of either 3-nortricyclyl tosylate (IX) or 5-norborn-2- enyl tosylate is 3-nortricyclyl acetate, some 5-norborn-2-enyl acetate also is formed. 7a,* By analogy, it might have been expected that some conversion of I to I1 and eventually to I11 might have occurred, with attendant deuterium scrambling. The nonobservance of such scrambling, at least under the conditions employed, shows that" leakage" to I1 (and to 111 ...
