title: Constitution of Grignard reagent RMgCl in tetrahydrofuran.
abstract: The constitution of Grignard reagent, RMgCl (R = Me, tBu, Ph or benzyl), was investigated in the solid state by means of X-ray crystallography and in THF by coldspray ionization mass spectrometry (CSI-MS). Three types of crystal structures, (a) [Mg2(mu-Cl3)(THF)6](+)*[RMgCl2(THF)](-), (b) R2Mg4Cl6(THF)6, and (c) [2Mg2(mu-Cl3)(THF)6](+)*[R4Mg2Cl2]2-, were identified, and MeMg2(mu-Cl3)(THF)4-6 were detected as major species of MeMgCl in solution.
