Embodiment 1

[0058] Embodiment 1, the synthesis of alkoxyiminodibenzocaprolactam derivatives (CAUWL-2010)

[0059] Add 3mmol of intermediate 1 (R1=H) or intermediate 2 (R1=Cl, Br, I) and 3.6mmol of alkoxyamine hydrochloride into 10mL of pyridine, stir at 90°C for 16 hours, and concentrate the reaction solution to After 2 mL, it was poured into water to produce a white solid, which was washed successively with appropriate amount of dilute hydrochloric acid and water, dried and recrystallized with ethyl acetate and petroleum ether (v / v=1:10) to obtain two isomers (Z and E) mixtures. The existence of cis-trans isomers was confirmed by HPLC-MS, and the ratio was basically 1:1. The physicochemical and mass spectrometry data of the compound CAUWL-2010 are shown in Table 2, and the proton nuclear magnetic resonance spectrum data of the compound CAUWL-2010 are shown in Table 3.

Embodiment 2

[0062] Embodiment 2, the preparation of compound CAUWL-2010 emulsifiable concentrate

[0063] Add 1-10g of compound CAUWL-2010, 5-15g of emulsifier, and 0.1-1g of penetrant into a 100ml volumetric flask, and then use solvents such as toluene, xylene, etc. to dilute to obtain an emulsifiable concentrate with a content of 1-10%.

Embodiment 3

[0064] Embodiment 3, the preparation of compound CAUWL-2010 wettable powder

[0065] Take 15-50 g of compound CAUWL-2010, 10-20 g of surfactant, and 30-75 g of white carbon black, mix and pulverize to obtain a wettable powder with a content of 15-50%.
