✦ Synopsis

Scheme 1. Reversible two-electron oxidative (a) and reductive coupling (b) to form CÀC bonds. R Et.

from triplet states of a ligand-to-metal charge transfer character that mix with metal-centered (ds/dp) states modified by Au ´´´Au interactions (LMMCT; S 3Au), whereas the high-energy emission at ca. 500 nm is attributed to metalperturbed intraligand phosphorescence.
