Experimental and theoretical rate coefficients for unimolecular reactions of gas-phase unsaturated organic peroxy radicals (RO2) are in excellent agreement. But the observed products question their contributions to autoxidation in Earth’s atmosphere.
The controlled cationic copolymerizations of isobutylene (IB) with alkenyl styrenes including 4-allylstyrene, p-(3-butenyl)-styrene and p-(5-hexenyl)-styrene were carried out in n-hexane/CH2Cl2 (6/4 v/v) at −80 °C using a t-BuCl/FeCl3/iPrOH initiating system.
Major advances have recently been made in understanding the biosynthesis and emission of floral volatiles, how their emission is shaped by abiotic and biotic factors, and which volatiles are involved in communicating with mutualists and parasites.
The increasing demand for herbal medicines as an alternative to synthetic drugs has gained significant attention due to their lower side effects and potential therapeutic benefits.
Butterflies use structurally highly diverse volatile compounds for communication, in addition to visual signals. These compounds originate from plants or a formed de novo especially by male butterflies that possess specific scent organs.
