Abstract

Complexes [Cu(SPh)2]-, [Cu(SPh)I]-and K[Cu(SPh)2(Ph)]+were observed by in situ electrospray ionization mass spectrometry (ESI-MS) analysis of the copper(i)-catalyzed C-S coupling reaction under catalytic reaction conditions indicating that they are intermediates in the reaction. A catalytic cycle was proposed based on these observations.
