摘要: Abstract Reactions of 3-functional substituted propenes like allylbenzene, allyl alcohols and ethers, N-allylamines, N-allylamides imides in the presence ruthenium(III) complexes having 1,3-diketonate ligands, mainly 2,4-pentadionate, were examined. It was found that course rate reaction between propene ruthenium complex depend on donor—acceptor properties functional group combined with a C-3 carbon. When this behaved medium or soft donor (allyl sulfides, N-allylimines), no double bond migration observed, whereas Ru(acac)3 underwent reduction to ruthenium(II) Ru(acac)2L2 type. Using Δ-(+)-Ru(acac)3 propenes, configuration determined also mechanism their formation proposed. The effect solvents Also, isotopic effects associated migration, substituents isomerization ofm- andp-substituted aryl ethers ligands catalytic activity type Ru(1,3-diket)3 studied.
