WebCleaving the C−C bonds in lignin to afford value-added low-molecular-weight aromatic products is promising but a challenging project. In this contribution, a mild and efficient strategy for one-step selective C−C bond cleavage in β-O-4 and β-1 lignin models has been developed over pyridinium-based photocatalysts. The strong electron ... WebSince most organic compounds have C-H bonds, a useful rule is that absorption in the 2850 to 3000 cm-1 is due to sp 3 C-H stretching; whereas, ... C–Cl stretch 850-550 cm-1; C–Br stretch 690-515 cm-1; The spectrum of 1-chloro-2-methylpropane are shown below. Figure 13. Infrared Spectrum of 1-chloro-2-methylpropane
