Syndiesis and Dynamic Behavior of 2,4-Pentadienyl(di-n-propyl)Borane... [Pg.47]

Pentadienyl(di- -propyl)borane 16 was prepared by the reaction of penta-dienyllithium with chloro(di-/i-propyl)borane in a mixture of hexane and THE at -30 °C (Scheme 2.5) [26],... [Pg.47]

Formally this corresponds to the [1,5] sigmatropic migration of the di-n-propylboryl group. However, it has been supposed that this dynamic behavior is instead caused by two consequent [1,3]-B migrations with the intermediacy of relatively unstable isomer 20a (Scheme 2.19). This conclusion was supported by the close values of the activation barriers of borotropic migrations in 20 (found from 2D EXSY NMR) and structurally similar Z-2,4-pentadienyl(di-n-propyl)borane 16b (see Table 2.1). [Pg.61]
