γ-Carboline synthesis enabled by Rh(
A redox-neutral Rh(III)-catalyzed C-H annulation of indolyl oximes were developed. The reaction exhibited a reverse regioselectivity, thus gave an exclusive and easy way for the synthesis of a wide range of substituent free γ-carbolines at C3 position with high efficiency. Deuterium-labeling experiments and kinetic anal. were preliminarily shed light on the working mode of this catalytic system. In the experiment, the researchers used many compounds, for example, 4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2Recommanded Product: 4-Iodo-1,2-dimethoxybenzene).
4-Iodo-1,2-dimethoxybenzene (cas: 5460-32-2) belongs to iodide derivatives. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. The C–I bond is the weakest of the carbon–halogen bonds. These bond strengths correlate with the electronegativity of the halogen, decreasing in the order F > Cl > Br > I. This periodic order also follows the atomic radius of halogens and the length of the carbon-halogen bond.Recommanded Product: 4-Iodo-1,2-dimethoxybenzene
