Syn- and anti-1-methyltricyclo[4.1.0.0(4,6)]heptan-2-ol derivatives (4
a and 4b) have been prepared. Their buffered solvolyses in anhydrous 2
,2,2-trifluoroethanol were studied. Anti dinitrobenzoate 4a solvolyzes
to give mainly m-xylene and two trifluoroethyl ethers (5 and 6). Solv
olysis of the syn mesylate 4b gives ,2,2-trifluoroethoxy)tricyclo[4.1.
0.0(3,5)]heptane (7). the product of a solvent trapped cyclopropyl cat
ion. (C) 1997 Elsevier Science Ltd.
