摘要:
The eta(6)-hydroquinone iridium complex [(eta(6)-H(2)Q) Ir(COD)]BF4 undergoes facile double deprotonation to the eta(4)-quinone anionic analogue. The latter has been shown to be the first example of an iridium complex that catalyzes 1,4 conjugate addition reactions of aryl boronic acids to electron deficient olefins. (C) 2008 Elsevier B. V.
