Dichloro[9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene]palladium(II) (CAS# 205319-10-4) is a useful inorganic catalyst used for Suzuki-Miyaura cross-coupling reactions, such as in the preparation of the selective estrogen receptor degrader GDC-0810. Dichloro[9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene]palladium(II) has also catalyzed the decarboxylative formylation of aryl halides with glyoxylic acid.
