Successive O−C/O−H and sp3 C−H Bond Activation of ortho Substituents in Allyl Phenyl Ethers and Phenols by a Ruthenium(0) Complex
摘要:
Successive O-C and sp(3) C-H bond activation. occurs in the reaction of Ru(COD)(COT) (1) [PMe3 with allyl 2,6-xylyl ether to give Ru[OC6H3(o-CH2)(o'-Me)](PMe3)(4) (4). Alternatively, 4 can be obtained by O-H and sp(3) C-H bond activation in 2,6-xylenol by 1/PMe3. In both cases, an eta(3)-allyl fragment could be responsible for the sp(3) C-H bond activation.
