名称:
Preparation of cationic (E)-σ-alkenyi palladium complexes having a P–O–N or a P–O–P tridentate ligand as a stabilized intermediate of palladium-catalysed stereoselective addition of methanol to acetylenes; characterisation, X-ray analysis and the reaction pathway
摘要:
具有P–O–N或P–O–P三齿配体的阳离子(E)-β-烯基钯配合物1通过在AgPF6和MeOH存在下,从cis-PdCl2(PNn= 1)[PN =o-Ph2PC6H4CH2O(CH2)n-2-C5H4N-P,N]或cis-PdCl2(POP)[POP = Ph2P(CH2)2O(CH2)2PPh2-P,P]与内部炔烃立体选择性制备;报道了1c的X射线晶体结构,并提出了形成1的分步氯配体提取机制。
