Phenylthio trimethylstannyl cuprate

Physical Data prepared in situ the THF soiution is dark red. Solubility soi THF. [Pg.333]

Preparative Methods lithium (phenylthio) (trimethyistanny -cuprate (2) is prepared by the addition of soiid phenyithiocop-per(I) to a THF solution of trimethylstannyilithlum (1) (eq 1). [Pg.333]

Handling, Storage, and Precautions should be prepared in dry soivent and used under an inert atmosphere. Since organotin compounds are toxic, reaction workup should be carried out in a fume hood. [Pg.333]
