A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 161265-03-8, Name is (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine), molecular formula is C39H32OP2. In a Patent，once mentioned of 161265-03-8, Quality Control of: (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine)
A pi – allyl palladium (II) complex and its preparation method and application (by machine translation)
The present invention provides a novel pi – allyl palladium (II) complex and its preparation method and application. This invention is through [Xantphos] PdI (Ph) and sulphone base joint alkene occurred after inserted into the reaction with the silver salt is generated by the reaction of allyl pi – ionic palladium (II) complex, the complex can be used for catalytic bi alkene compound double-funtionalization reaction, at the same time introduced into the bi alkene molecule C – C and C – O key. The invention is characterized in that: the complex can be realized to the metal catalytic second line alkene compound beta – H to eliminate, competition reaction inhibition of aggregation or the like, so that a single reaction, and the reaction area and solid selective control.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Quality Control of: (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine), If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 161265-03-8, in my other articles.
