Generation and trapping of 1,3-dilithio-1,3-disila-isoindolines, the first example of dianions of functionalized silanes
Abstract
N-Alkyl-1,3-dichloro-1,3-disila-isoindolines are reduced with lithium naphthalenide at –78 °C to give the 1,3-dilithio drivatives which can be trapped with electrophiles.
