• W1590014684 abstract "[17830-50-1] C40H32O3P2Pd (MW 729.05)InChI = 1S/2C18H15P.C4H2O3.Pd/c2*1-4-10-16(11-5-1)19(17-12-6-2-7-13-17)18-14-8-3-9-15-18;5-3-1-2-4(6)7-3;/h2*1-15H;1-2H;InChIKey = SZTCAWKWIIWPGZ-UHFFFAOYSA-N(bis(triphenylphosphine)(maleic anhydride)palladium(0) 1 is an isolable, moderately air-stable, palladium(0) complex that can be used in a variety of reactions where a preformed, organic-soluble palladium(0) complex is required as a catalyst, a catalyst precursor or a stoichiometric reagent. To date, however, almost all of the reported uses of 1 have been in palladium-catalyzed dimerization of 1,2- or 1,3-dienes.)Alternate Name: bis(triphenylphosphine)(maleic anhydride)palladium; (maleic anhydride)bis(triphenylphosphine)palladium; [(3,4-η)-2,5-furandione]bis(triphenylphosphine)palladium; (2,5-furandione)bis(triphenylphosphine)palladium.Form Supplied in: yellow crystalline solid.Preparative Methods:1, 2 maleic anhydride (98 mg, 1 mmol) was dissolved in THF (15 mL) and added dropwise over 10–20 min via a pressure-equalization funnel to a nitrogen blanketed solution of tetrakis(triphenylphosphine)palladium(0) (1.155 g, 1 mmol) in benzene (30 mL). The resulting mixture was stirred for additional 30 min at room temperature, after which the solvent was removed under reduced pressure. The resultant yellow oil was redissolved in a mixture of benzene and methanol (2:1, 15 mL) and filtered. Benzene (40 mL) was added to the filtrate and the resulting mixture was cooled in a refrigerator. Yellow crystals were separated from solution overnight. The crystals were isolated by filtration, washed with a mixture of benzene, methanol, and hexane (2:1:5), and dried in vacuo to yield 630 mg of 1 (86%).Purification: recrystallized from benzene, washed with a mixture of benzene, methanol, and hexane (2:1:5), and dried in vacuo.2Handling, Storage, and Precautions: limited stability in air, reported to be of the order of hours.1Disposal: use typical precautions for heavy metals." @default.
