Green synthetic method of kresoxim-methyl

The invention belongs to the technical field of fine chemical engineering, and particularly relates to a green synthetic method of kresoxim-methyl. The method comprises the following steps: carrying out nitrous nitrification by using 2-methylbenzyl cyanide as an initial raw material, carrying out methylation, carrying out hydrolytic methylation or hydrolytic esterification, carrying out bromination and carrying out an etherification reaction to obtain the high-content kresoxim-methyl. The method provided by the invention has a short reaction period, a high conversion rate, and excellent product quality, changes the defect that high-concentration hydrochloric acid gas is used for preparation in a traditional process, and has the advantages of simple operation steps, simple equipment, low energy consumption, a short period, high productivity and environmental protection.

Cu-Mediated Stereoselective [4+2] Annulation between N-Hydroxybenzimidoyl Cyanide and Norbornene

A Cu-mediated stereoselective [4+2] annulation between N-hydroxybenzimidoyl cyanides and norbornene (NBE) has been developed for the synthesis of 4H-1,2-oxazin-4-ones. The reaction proceeds through sequentially forming C-O/C-C bonds. The advantage of this reaction includes high stereoselectivity, excellent yields, as well as simple and mild reaction conditions. A total of 26 examples are presented along with some control experiments.

Reaction of the Silver Salts of Arylnitroacetonitriles with 9-Bromofluorene. Synthesis of 9-(α-Cyanoarylidene)fluorenes

The silver salts 1a-d react with 9-bromofluorene to give both C- and O-alkylated products 2 and 3.The latter decompose to yield 9-fluorenone and the α-cyanooximes 5.The products 2 upon treatment with NaOH/EtOH eliminate HNO2 to afford 9-(α-cyanoarylidene)fluorenes 4 in 80percent yield. 9-Chloro-9-phenylfluorene reacts with salt 1a to give only C-alkylated product 6 in 70percent yield.
