Triphenylphosphine oxide supported on non-cross-linked maleimide–styrene copolymer: application as a novel Hendrickson reagent
摘要:
A new triphenylphosphine oxide reagent linked to a linear maleimide-styrene copolymer is synthesized. This phosphine-bound copolymer is converted to copolymer-supported triphenylphosphine ditriflate as a novel Hendrickson reagent by treatment with triflic anhydride. This reacts rapidly in various dehydration reactions such as anhydride, ester and amide formation. This linear and soluble support is also easily recovered and recycled several times without loss of efficiency. (C) 2008 Elsevier Ltd. All rights reserved.
P-Arylation in water has been developed via cross-coupling of arylhalides with diphenylphosphine oxide (Ph2P(O)H) and (RP)-(−)-menthyl benzylphosphinate catalyzed by NiCl2·6H2O/Zn under relatively mild conditions.
NiCl 2 ·6H 2 O / Zn催化的芳基卤化物与二苯基膦氧化物(Ph 2 P(O)H)和(R P)-(-)-薄荷基苄基次膦酸酯的交叉偶联已开发了水中的P-芳基化。相对温和的条件。
Visible-Light-Induced Metal-/Photocatalyst-Free C–H Bond Imidation of Arenes
In this study, a visible-light-induced intermolecular C-H bond imidation of arenes was achieved at ambient condition. By using simple phthalimide with (diacetoxyiodo)benzene and molecular iodine, direct metal-/photocatalyst-free C-N bond formation was achieved. The imidation protocol was designed by using time-dependent density functional theory calculations and experimentally demonstrated for 28 substrates
efficient CPbondformation reaction of diarylphosphine oxides with aryl iodides was achieved by combining nickelcatalysis and visible‐light‐induced photoredoxcatalysis. This dual‐catalytic reaction showed a broad substrate scope, excellent functional group tolerance, and afforded the corresponding products in good to excellent yields. Compared with the previously reported use of photoredox/nickel dual
