Tanner, David,Wennerstroem, Olof,Norinder, Ulf,Muellen, Klaus,Trinks, Rainer
, p. 4499 - 4502 (1986)
A new synthesis of paracyclophene (1) is presented.On reduction, (1) forms a stable dianion which is neither diatropic nor paratropic.The apparent high symmetry of the dianion and the observed NMR chemical shifts are best explained by a rapid inter
Synthesis and Studies of Some 4>Ferrocenophanetetraenes
Tanner, David,Wennerstroem, Olof
, p. 529 - 536 (2007/10/02)
Ferrocenophanetetraenes 1-5, in which the two cyclopentadienyl rings are linked by a conjugated chain of double bonds and para-substituted benzene rings, have been synthesized via multiple Wittig reactions.The extent of planarity and conjugation in these
