suzuki reaction | [Definition]
ChEBI: 1,2-bis(diphenylphosphino)ethane is a tertiary phosphine and a member of diphosphanes. It has a role as an allergen. | [Purification Methods]
Recrystallise it from aqueous EtOH or *C6H6. The dimethiodide, when recrystallised from MeOH has m 305-307o, and the dioxide when recrystallised from toluene or DMF (needles), or *C6H6 (plates) has m 252-254o (276-278o) [Isslieb et al. Chem Ber 92 3175 1959, NMR: Aquiar et al. J Org Chem 29 1660 1964, B.ckvall et al. J Org Chem 52 5430 1987]. [Beilstein 16 IV 958.] |
