The direct conversion of C-H bonds to C-B bonds is a recently developed class of metal-catalyzed C-H bond functionalization. The conversion of C-H bonds to C-B bonds is both thermodynamically and kinetically favorable. Furthermore, C-B bond is easy to convert to other formations. Hence, significant progress has been made toward the development of systems that catalyze such borylation reactions of C-H bonds in alkanes, alkenes, and arenes in high yields and with high selectivity. For these studies, powerful analysis method is essential for development of efficient reaction conditions: catalyst, ligand, base, solvent, time and temperature. Traditional methods required expensive instruments or specific materials, such as nuclear magnetic resonance spectroscopy (NMR), infrared spectroscopy (IR), mass spectrometry (MS), gas chromatography (GC), and high-performance liquid chromatography (HPLC). To address this problem, we developed paper-based colorimetric sensor for C-H borylation using Bis(pinacolato)diboron (B2Pin2). Iodine resulted from B2Pin2, the residue of brylation and I2O5 in paper makes complex with starch. Then the complex turn up violet color. We can determine yield of the reaction by analyzing color using scanner. This paper based colorimetric sensor for C-H borylation is easily and economically accessible in any general laboratory(analysis using scanner).
