We report a highly efficient and selective catalytic system, ABNO (9-azabicyclo-[3.3.1]nonane N-oxyl)/HNO3, for the aerobic oxidation of substituted furans to cis-2-ene-1,4-diones under mild reaction conditions using oxygen as the oxidant. The catalyst system is amenable to various substituted (mon-, di-, and tri-) furans and tolerates diverse functional groups, including cyano, nitro, naphthyl, ketone
我们报告了一种高效和选择性催化体系 ABNO (9-azabicyclo-[3.3.1] nonane N -oxyl)/HNO 3,用于将取代的呋喃有氧氧化为顺式-2-ene-1,4-二酮以氧气为氧化剂,反应条件温和。该催化剂体系适用于各种取代的(单-、二-和三-)呋喃,并耐受多种官能团,包括氰基、硝基、萘基、酮、酯、杂环,甚至甲酰基。基于对照和18个O标记实验,提出了氧化的可能机理。

A device, system, and method of controlling pests are disclosed. A pest control device includes a sensor having a sensor cell and a controller. A surface of the sensor cell is coated with an agent that reacts with a targeted biochemical analyte secreted by pests. The controller is coupled to the sensor and is configured to receive sensor data from the sensor cell indicative of a rate of change in sensor mass detected on the surface of the sensor cell, determine whether the rate of change in the sensor mass based on the received sensor data exceeds a predefined threshold rate, and transmit a pest detection alert notification to a server in response to a determination that the rate of change exceeds the predetermined threshold rate.

Compositions and methods for controlling and/or repelling bedbugs are provided. The compositions comprise one or more compounds having bedbug repellant activity. Such compounds may be, for example, naturally occurring semiochemicals or structural or functional analogs of naturally occurring semiochemicals. Exemplary compounds are compounds of general formula (I).
A composition for attracting bed bugs, the composition comprising the five compounds (E)-2-hexenal, (E)-2-hexenoic acid, (E)-2-octenal, 2-octenoic acid and 2-hexanone, a trap comprising these five compounds and methods of attracting and detecting bed bugs using the five compounds, are disclosed.
