Tetrakis iodo copper

The most recent lUPAC name for the above compound is tetra-/x3-iodo-tetrakis [triethylarsine copper (I)]. [Pg.137]

Preparation.1 A solution of 2 eq. of vinyllithium (Alfa Inorganics) in THF is added slowly to a THF solution of 1 eq. of tetrakis[iodo-(tri-n-butylphosphine)copper(I)] (2, 400 3, 278) at —78° under N2 with stirring. The complex is blue-black. [Pg.448]

Siddall, Biskup, and Fried3 achieved a simple, direct synthesis of the iso-prenoid (3) by the reaction of the Grignard reagent from 4-methylpent-3-enyl bromide (2) with methyl but-2-ynoate (1) in the presence of 1.5 equivalents of tetrakis[iodo(tri-n-butylphosphine)copper(I)]. The reaction must be carried out below —50°. This reaction is an example of conjugate addition of organometallic... [Pg.142]

Preparation. Whitesides et al. prepared the reagent by the reaction of one equivalent of tetrakis[iodo(tri-n-butylphosphine)copper(I)]2 with two equivalents of commercial n-butyllithium at —78° in THF. [Pg.245]
