Multicomponent Reactions Silanes are an important class of compounds in chemistry and reactions based on the use of compounds bearing silyl groups are commonly used synthetic tools. A reaction scheme has been developed using ZnCl2 as a catalyst in a three‐component coupling of alk‐2‐ynals, 1,3‐dicarbonyls, and silanes in a process with high atom economy in the absence of organic solvents. For more...
A three‐component coupling of alk‐2‐ynals, 1,3‐dicarbonyls and silanes is reported. ZnCl2 serves as an inexpensive and low‐toxic catalyst for the overall transformation, which involves Knoevenagel condensation, cyclization, and carbene SiH bond insertion. The process takes place with high atom economy in the absence of organic solvents and shows a broad scope. This reaction is also applicable to...
