Procedure
-
Reagents for metallophotoredox cross-coupling reactions (HPMC encapsulated) (one capsule) was added to a solution of 5-bromopyrimidine (95 mg, 0.60 mmol) and morpholine (78 μL, 0.90 mmol, 1.5 eq.) in DMAc (6 mL) at r.t. The solution was placed at a distance of 3-5 cm from Blue LED lamp and stirred for 24 hours at 60 °C. The reaction mixture was then filtered through Celite. The filtrate was diluted with sat. Na2SO4 aq. (15 mL) and extracted with ethyl acetate (15 mL x 5). The organic layer was dried over sodium sulfate, concentrated under reduced pressure. The crude product was purified by silica gel column chromatography (dichloromethane:methanol = 10:1) to afford 4-(pyrimidin-5-yl)morpholine (84 mg, 85% yield) as a pale brown solid.

Experimenter’s Comments
-
The reaction mixture was monitored by GC.
Irradiation of visible light was performed with Kessil A160WE Tuna Blue 40W x 2.
DMAc was degassed with nitrogen for 30 minutes before use.
The shape of the capsule is like below image and each capsule includes NiBr2(dme) (ca. 0.03 mmol), [Ir[dF(CF3)ppy]2(dtbbpy)]PF6 (ca. 0.12 μmol), and DABCO (ca. 1.1 mmol).
The material of the capsule is water-soluble HPMC (hydroxypropyl methylcellulose).
