A practical and promising protocol was developed for S-arylations of various thiols with different substituted aryl halides. The reactions were readily facilitated to afford desired thioethers under mild conditions in good to excellent yields. The versatility, air-stability, operational simplicity of

The structure of the alkylzinc-tetramethylethyl-enediamine (TMEDA) cluster cation 3 has been determined in the gas phase by a combination of tandem mass spectrometry, infrared multiphoton dissociation (IRMPD) spectroscopy, and DFT calculations. Both sets of experimental results establish the existence of
