A new benzannulation reaction
A new benzannulation reaction was discovered. The reaction involves intramolecular attack into a carbon-carbon triple-bond by the alpha position of a beta-ketoester under acidic conditions. Four different beta-ketoester ...
Matrix reactions of silicon difluoride as studied by infrared spectroscopy
Infrared matrix isolation spectroscopy has been employed to characterize monomeric silicon difluoride. Warm-up experiments show the development of several sets of new bands which indicate that this molecule polymerizes ...
The reactions of silicon difluoride with sulfur compounds: the silicon-sulfur bond
The reactions of silicon difluoride with several sulfur containing compounds have been investigated in an attempt to synthesize compounds containing the silicon-sulfur bond. Of the previous reactions of silicon difluoride ...
