All compounds were used directly without further purification.
Preparation of 3-azidopropyltrimethoxysilane (AzPTMS). The AzPTMS precursor was synthesized by adding 2 g of Cl-PTES, 1.08 g sodium azide and 1.29 g tetrabutylammonium bromide) in 100 mL ACN, which was stirred and refluxed at 90 o C for 24 h under nitrogen atmosphere. Then, the ACN solvent was removed by rotary evaporation at 80 o C under a vacuum of 0.2 bar. The residual mixture was suspended in cyclohexane and filtered with filter paper. The residual cyclohexane was further removed by rotary evaporation at 80 o C under pressure of 0.2 bar and the oily Az-PTMS can be finally obtained. Yield: ~1.3 g, 65 %. 1 H NMR (400 MHz, CDCl3): δ (ppm) 3.82 (s, 9H), 3.65 (t, 2H, 8.25 Hz), 1.24 (m, 2H), 0.75 (t, 2H, 8.31 Hz).

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
