Part 1. B-ferrocenylalkyl carbonium ions. Part 2. The stereospecific syntheses of the exo and endo isomers of a-hydroxymethyl-1,2-tetramethyleneferrocene
Part I The solvolysis mechanism of [Beta]-ferrocenylalkyl tosylates is discussed. Evidence is presented which shows that solvolysis occurs with preferential participation of the interannular electrons of the ferrocene moiety leading to intermediate formation of very stable carbonium ions. The produ...
