Neighboring groups, alkenes hydrogen

Q Base (B ) attacks a neighboring hydrogen and begins lo remove the H at the same time as the alkene double bond starts to form and the X group starts to leave. [Pg.386]

Some cationic Rh- and Ir-phosphine complexes have been used for diastereoselective hydrogenation of chiral allylic and homoallylic alcohols. Here, the preexisting chirality of the 5p -hybridized carbons induces new asymmetry on the neighboring alkenic diastereofaces through coordination of the hydroxy group to the transition metals (see Section 3.2.1). [Pg.462]
