Carbonylative formation of N-acetyl-2,6-difluorobenzamide through N–H bond activation of 2,6-difluorobenzamide with Ni(II) complex supported with phosphine ligands
摘要:
Fluorinated imide, N-acetyl-2,6-difluorobenzamide (C6H3F2-2,6)C(O)NHC(O) Me 2, could be obtained through one-pot reaction of NiMe2(PMe3)(3) with 2,6-difluorobenzamide (C6H3F2-2,6)C(O)NH2 1 in CO atmosphere. A postulated reaction mechanism via N-H bond cleavage and carbonylative reductive elimination on nickel center was partly experimentally confirmed. An important intermediate (C6H3F2-2,6)C(O)HNNiMe(PMe3)(2) 3 was isolated and structurally characterized. (C) 2011 Elsevier B. V. All rights reserved.

A highly selective synthesis of acyl isoureas and imides from readily accessible amides, isocyanides, alcohols and carboxylates based on reaction solvent selection is described. In the presence of a catalytic amount of [1,1′‐bis(diphenylphosphino)ferrocene]dichloropalladium(II) and cupric acetate, treatment of amides and isocyanides in alcohols at 60 °C provided acyl isoureas in high yields.

The invention relates to substituted pyrimidine ether compounds having general formula I:
The groups are as defined as specification.
The compounds of formula I show high insecticidal activities for imagoes, larvae and nits of harmful acari and insects in the agricultural, civil and zoic fields, especially show excellent insecticidal activities for harmful acari such as Tetranychus cinnabarinus. Good effects can be obtained at very low dose. The compounds also exhibit preferably fungicidal activity. Wherefore, the invention also comprises the uses of compounds of formula I as insecticides, acaricides and/or fungicides in agricultural and other fields.
本发明涉及通式 I 的取代嘧啶醚化合物:
基团如说明书所定义。
式 I 的化合物对农业、民用和动物领域中的有害吸虫和昆虫的成虫、幼虫和虫卵具有很高的杀虫活性,特别是对有害吸虫(如朱砂蝇)具有很好的杀虫活性。用很低的剂量就能获得很好的效果。这些化合物还具有较好的杀真菌活性。因此,本发明还包括将式 I 化合物用作农业和其他领域的杀虫剂、杀螨剂和/或杀菌剂。
