Synthesis of Dialkyl Ethers from Organotrifluoroborates and Acetals
The formation of ethers by C−O bond formation under harsh basic or acidic conditions is an entrenched synthetic disconnection in organic chemistry. We report a strategic... -
Magnetic Fluorescent Delivery Vehicle Using Uniform Mesoporous Silica Spheres...
We synthesized uniform pore-sized mesoporous silica spheres embedded with magnetite nanocrystal and quantum dots. The magnetic separation, luminescent detection, and controlled... -
Remarkable Effect of Pore Size on the Catalytic Activity of Mesoporous Silica...
The catalytic activity of mesoporous silica (MCM-41) for the acetalization of cyclohexanone shows a volcano-shaped dependence on the pore diameter. The diameter of the... -
