C-H activation has been recognized as an increasingly viable tool in mol. sciences, but organometallic C-C activation is scarce, and limited to precious and toxic metal catalysts. Herein, versatile C-C activations by a robust base-metal catalyst in water has been disclosed. Thus, an inexpensive manganese(I) catalyst enabled C-C functionalizations with excellent levels of chemo- and position-selectivities, setting the stage for versatile C-C allylations, C-C alkenylations and C-C alkylations in water. The manganese(I) catalyst outperformed commonly used copper, iron, palladium, rhodium and ruthenium complexes, and the C-C activations occurred on steroid and amino acid motifs. Detailed kinetic and computational studies provided strong support for a kinetically relevant C-C manganesation. In the experiment, the researchers used many compounds, for example, 2-(m-Tolyl)pyridine (cas: 4373-61-9Recommanded Product: 4373-61-9).
2-(m-Tolyl)pyridine (cas: 4373-61-9) belongs to pyridine derivatives. Pyridine is diamagnetic and has a diamagnetic susceptibility of −48.7 × 10−6 cm3·mol−1.The molecular electric dipole moment is 2.2 debyes. The standard enthalpy of formation is 100.2 kJ·mol−1 in the liquid phase and 140.4 kJ·mol−1 in the gas phase. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.Recommanded Product: 4373-61-9
