Abstract
- The title reaction of silylethynyl 2,6-(tBu)<subscript>2</subscript>phenyl ethers took place in the presence of a palladium catalyst and pivalic acid to give 2-silylmethylenechromanes. The initial products were converted by treatmentwith acetic acid to thermodynamically stable 4H-chromenes, which were further reacted with activated aldehyde and ketone. [ABSTRACT FROM AUTHOR]
