基于结构-活性关系 乙恶唑设计并合成了一系列的2-(2,6-二氟苯基)-4-(4-取代的苯基)-1,3-恶唑啉4a-y和苯甲酰基苯基脲。发现大多数这些化合物显示出优异的杀螨活性。当浓度为2.5 mg L -1时,它们对蜘蛛螨的卵和幼虫的死亡率都达到85%以上。一些化合物还表现出优异的杀虫活性。2,4-二苯基-1,3-恶唑啉的4-苯基上的取代基的位置和类型对活性有很大影响。2-(2,6-二氟苯基)-4-(2-Cl-4-(4-Cl-苯氧基)苯基)-1,3-恶唑啉(4r)在2.5 mg L -1下表现出100%的杀螨作用,对甜菜夜蛾和小菜蛾的死亡率分别为12.5 mg L -1和65%和93%,几乎与乙恶唑。新发现的结构-活性关系也可能有益于进一步的杀螨剂/杀虫剂开发。

[reaction: see text] Ullmann-type diaryl ether synthesis can be performed at 90 degrees C using either aryl iodides or aryl bromides as the substrates under the assistance of N,N-dimethylglycine.
A practical and mild strategy has been developed for the cross-coupling of O-arylation of phenol with differently substituted aryl halides and heteroaryl iodides using lowcatalystloading of copper iodide underlow operating temperature in DMF with TMHD as the ligand and Cs2CO3 as the base. This method tolerates a variety of functional groups including sterically hindered phenols and heteroaryl iodides

We have developed an efficient and inexpensive bimetallic catalyst FeCl3, CuO, and rac-BINOL that could promote N,O-arylation of aliphatic, arylamines, and phenols. The cross-coupling reaction conditions have high tolerance of various functional groups. This versatile and efficient iron/copper-cocatalyst can widely be used in the synthesis of the compounds containing (aryl)C-N or (aryl)C-O(aryl) bond.
The present invention provides a composition comprising a combination of components A) and B), wherein component A) is a compound of formula (I) and the component (B) is a further fungicide, insecticide or herbicide.
