(X = F, Cl, Br or I; E = S or Se, R most often Me, sometimes Et or iPr, R2 = c-(CH2)n) Typical syntheses involved direct reaction of the BX3 and ER2 in the absence of a solvent, whilst others used alkanes, CCl4, CH2Cl2 or CS2 as solvents [16], [17], [18], [19],...
well-filtered at 0.45 μm. Data were processed using the binding software of the Astra 6.1 package. Molecular weights were obtained with the Zimm order 1 method using angles from 34.8° to 142.8° and with a dn/dc of 0.15 mL/g. Analysis from VD used the Einstein/Simha formula for the ...
for 1 min with a vortex. Vitamin C was used as the positive control and ethanol was used as blank. The absorbance was measured at 517 nm with a visible light spectrophotometer. The experiment was carried out in triplicate. Radical scavenging activity was calculated using the following formula:...
The acid was manually removed and the dark green solid was collected, milled and profusely washed with Et2O/CCl4 (1:1). Yield: 0.42 g (56%). Anal. Calcd. (%) for 1a–1Et2O: C, 50.28; H, 3.96. Found (%): C, 50.02; H, 4.57. FT-IR (cm−1): 3069w, 2973w, 2878w, ...
4.3.7. Synthesis of 1,3,5-Tris(bromomethyl)benzene (β) A mixture of mesitylene (2.8 mL, 20 mmol), N-bromosuccinimide (10.62 g, 60 mmol), and benzoyl peroxide (0.11 g) in CCl4 (30 mL) was stirred and heated under N2 for 14 h at 90 ◦C. The reaction mixture was monitored ...
