In cyclopentadiene systems, 1,5-shift of triply bonded groups is much slower than that of doubly bonded groups, whereas in the cycloheptatriene systems (34) and (29), as well as in (21) and (19), CN and CHO groups have very similar migratory tendencies.In
Divergent Relative Migratory Aptitudes of Double and Triple Bonded Groups in Cyclopentadiene and Cycloheptatriene Systems
Battye, Peter J.,Jones, David W.
, p. 1458 - 1460 (2007/10/02)
In cyclopentadiene systems 1,5-shift of triple bonded groups is much slower than that of double bonded groups whereas in the cycloheptatrienes (1) and (2), CN and CHO have very similar migratory aptitudes and (2; X = CCCOPh) rearranges at 60 degC whilst (1; X = E-CH=CHCOPh) is unchanged at this temperature; variations of strain in the bridged transition states may explain these results.
