Formaldehyde solution can be activated by adding the catalytic amount of lanthanide triflate. This activated formaldehyde solution was employed for the smooth hydroxymethylation reaction of silyl enol ethers.[1] Formaldehyde solution reacts with silyl enol ethers to afford the corresponding hydroxymethylated adducts in high yields.[2] Application Formaldehyde solution was used to prepare the formaldehyde stock solution for the development of transparent sol-gels with entrapped sensitive and selective reagents for the detection of formaldehyde in air.[3] It may be used in the preparation of nanocrystalline metal (Cu, Hg, Zn, Bi, Pb) sulfides having different shapes and different particle sizes.[4] Other Notes The article number 15512-4X2.5L-R will be discontinued.
