2D NMR experiments can provide a wealth of information to aid in the structural elucidation of chemical compounds. Of the many 2D NMR experiments available, the homonuclear correlation spectroscopy (COSY) sequence is one of the most popular and is used to identify which spin systems are directly coupled to each other. As an example, the 1H-1H COSY spectrum of 1-propanol recorded on the NMReady-60 is shown below in Figure 1.Read More
With great advances in areas such as metabolomics, quantitative NMR, and online analysis, 2017 was a very exciting year for NMR in general, but specifically so for Benchtop NMR! Benchtop NMR has continued to make NMR, one of the strongest characterization techniques, become a mainstream staple in teaching and research laboratories. As users realize how easy it is to incorporate the NMReady-60 spectrometers into their laboratories, they have continued to breakthrough into new and exciting applications.Read More
Wishing everyone a warm and happy holiday season!
The Wittig reaction is a high-yielding, versatile synthetic procedure used to construct carbon-carbon double bonds. Unlike other sp2 bond forming reactions this can be used to provide convenient access to a cis– stereochemistry. At the time the reaction was discovered by Georg Wittig, this cis– confirmation was not reliably afforded by other synthetic means. To …Read More
