SiliaBond® Reagents Kit For Microwave Applications
In recent years, μ-wave synthesizers have taken organic chemistry by storm. Fast kinetics, higher yields, excellent purities, wide compatibility of solvents, and their applicability to a variety of reactions and applications, makes them very important tools in the laboratory. After their introduction, chemists started to use supported reagents for solution-phase synthesis. The polymer supported reagents commonly used, although very useful, have drawbacks in -wave synthesizers: swelling and heat stability. The high temperatures generated inside these synthesizers put stress on these resins. Also, because of the small reaction volumes, the swelling of the resins can be problematic. Silica-based reagents on the other hand, do not suff er from such shortcomings. They are heat resistant and they do not swell.
For your convenience, SiliCycle and CEM Corporation had developed a silica-based reagents kit for μ-wave applications that contains SiliaBond® reagents for diff erent types of reactions (amide synthesis, reductive amination, Suzuki couplings) as well as electrophile, nucleophile, and metal scavenging reactions that demonstrate the eff ectiveness of these reagents in μ-wave applications. You will find general experimental procedure related to each application.
