Mechanistic studies support a pathway in which regioselectivity is dictated by the choice of counterion associated with the Rh center. Non-coordinating counterions, such as SbF6–, allow for η4-diene coordination to …
Webaddition of (1) to one equivalent of 1,2-dithioethane (11) and two equivalents of NaOCH3 led to the dithio-SMC (12) as a stable amorphous red-colored sodium salt. The absorption spectrum of (12) in DMSO was similar to that of the acyclical thio-Meisenheimer complex (Scheme 8). In both cases the absorption maxima were at 454 nm, 534 nm, and 564 nm.
