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 NÌI2 · 6H2O ( 1.68 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 C31H32I2NÌO2P2 ( 1,1 g, 68%) as dark brown crystals. Like in the chloro compound (see ref. 1), the Ni is coordinated by a distorted tetrahedra, mean distances: Ni-I: 253.3(1) pm, Ni-P: 228.0(2) pm, angle I-Ni-I: 121.92(5)°.
