The recent independent reports by Stang'and Kowalski2 on the first silylations of ynolate anions on oxygen prompt us to disclose our preliminary results on the generation and trapping of ynolate dianions directly generated from the readily available precursor, 2, 3- dihydrofuran (1). Metalation of 2, 3-dihydrofuran (1) to produce a-lithiodihydrofuran (2) is a well-established reaction, and the carbanion structure has been studied by I3C NMR., ...
