Rather different derivatives of the new title compuond 7 were synthesized by routes A - H (Table 2 and 3).The effects of substituents and reaction routes on the E/Z ratios (NMR) is discussed.Replacement of SiMe3 in 7 by RCO- and MeSO2- yields other alkenes with donor (O - X) and acceptor groups (CN) at the same C-atom.Their opposite effects on the β-C-atom is estimated from the corresponding 1H- and 13C-NMR signals.
