Abstract
Source of material: A solution of [(-)-2,2-dimethyl-4,5-bis(diphenylphosphinomethyl)-l,3-dioxolane][(-)-diop] (1.0 g, 2 mmol) in dry dichloromethane (5 ml) was added to a stirred solution of NiBr2 (0.87 g, 4 mmol) in dry ethanol (15 ml). After stirring for 10 min the precipitate was filtered off, washed with cold ether and dried under reduced pressure to give Сз1Нз2Вг2К102Р2 · CH2CI2 (1,1 g, 83%) as brown crystals,
