Synthesis of thioureas in ionic liquid medium

A highly efficient procedure for the synthesis of symmetrical thioureas by means of simple condensation of primary amines and carbon disulfide in 1-butyl-3-methylimidazolium chloride [BMIM][Cl] as a cheap and commercially available ionic liquid is presented. This procedure works for aromatic and aliphatic primary amines and give high to excellent yields of symmetrical thioureas without need for any catalyst or tedious work-up.

Synthesis and structure of two new (guanidinate)boron dichlorides and their attempted conversion to boron(i) derivatives

To test the feasibility of the guanidinate architecture for the support of boron(i) carbene analogues the energy gap between the singlet and triplet states of the model compound, [Me2NC{N(Ph)}2B:] (7), has been probed by both DFT and second order Moller-Plesset (MP2) methods. The singlet state is calculated to be more stable than the triplet state by between 6.0 and 10.1 kcal mol-1. The new (guanidinate)boron dichlorides [Ph2NC{N(Mes)2]BCl2 (14) and [Ph 2NC{N(Dipp)2]BCl2 (15) have been prepared and characterized by single-crystal X-ray diffraction. Attempts to reduce 14 and 15 to the corresponding boron(i) species were not successful.

Sterically bulky thioureas as air- and moisture-stable ligands for pd-catalyzed heck reactions of aryl halides

We demonstrate that sterically bulky N,N′-disubstituted cyclic thiourea-Pd(0) complexes are air- and moisture-stable and highly active catalysts for palladium-catalyzed Heck reaction of aryl iodides and bromides with olefins (TONs up to 500 000 for the reaction of Phl and methyl acrylate). Even activated aryl chlorides can undergo complete conversion in Bu 4NBr in the presence of 1 mol % Pd catalyst.
