Abstract

The 2-furfuryldiazomethanes 3c and 3d, with trimethylsilyl and trimethylstannyl groups, respectively, in the 5-position, were generated from the sodium salts of the corresponding tosylhydrazones and matrix-isolated in argon at 10 K. Photolysis of the diazo compounds 3 resulted in the formation of the highly unsaturated acylsilanes and acylstannanes 2 in clean reactions. Comparison of the experimentally obtained IR spectra with those obtained from DFT calculations revealed that compounds 2 were formed in their thermodynamically less favorable (Z) conformations.
