Solvent-free mesityllithium: Solid-state structure and its reactivity towards white phosphorus

The donor-free mesityllithium was prepared from the reaction of MesBr with n-BuLi in diethyl ether at -78°C. The solid-state structure of unsupported mesityllithium consists of C2Li2-rings composed of two LiMes units, which interact with adjacent dimers [LiMes]2, forming a polymeric infinite chain along the crystallographic c-axis (monoclinic space group, P21/n). The structure of donor-free mesityllithium reveals short contacts between the C atoms of the mesityl rings and the lithium atoms of neighbouring [LiMes]2 units. The structure determination of LiMes was performed by X-ray powder diffraction. In addition we have investigated the reaction of LiMes with Me3SnCl and P4 for our understanding of the reactivity of donor-free mesityllithium. The heterogeneous reaction of donor-free mesityllithium with Me3SnCl produces conveniently the stannylated mesitylene Me3SnMes (triclinic, space group P1). White phosphorus reacts with three equivalents of unsupported mesityllithium in benzene to give Li3P4Mes3. In this context it should be noted that a tetraphosphide with an identical LiP-core as in Li3P4Mes3 had been formed in the 1:3 reaction of P4 with the silanide Li[SitBu3]. The tetraphosphide Li3P4Mes3 was analyzed using X-ray crystallography (monoclinic, space group C2/c).

Selective and mild synthesis of mono- and diarylated group 13-15 halides using [CuMes]n, a readily available, thermally stable organocopper(I) reagent

The use of mesitylcopper, a soluble, thermally stable arylcopper compound, was investigated as an alternative to less selective organolithium and Grignard reagents or toxic mercury, tin, and organozinc compounds. [CuMe]5·toluene (1) was found to readily react with various main group metal halides MXn and RMXn (M = B, Sn; X = Cl, Br; R = nBu, Ph, 1,1′-fc) to give, depending on the stoichiometry of the reactions, monoarylated, diarylated, or mixed substituted species MesMXn-1, Mes2MXn-2, and MesRMXn-1 (2-5) in high yields.
