A rhodium complex catalyzed C−Se bond formation between diheteroaryl diselenides and acid fluorides in the presence of triphenylphosphine to provide heteroarylselenyl esters in good yields. The reaction was applicable to five‐ and six‐membered heteroaryl compounds. The heteroarylselenyl esters can be used as heteroaryselenating reagents in the synthesis of heteroaryl selenides, as shown by a platinum‐catalyzed addition reaction with 1‐octyne.

In complex structures such as flowers, organ–organ interactions are critical for morphogenesis. The corolla plays a central role in attracting pollinators: thus, its proper development is important in nature, agriculture, and horticulture. Although the intraorgan mechanism of corolla development has been studied, the importance of organ–organ interactions during development remains unknown. Here, using corolla mutants of morning glory described approximately 200 years ago, we show that glandular secretory trichomes (GSTs) regulate floral organ interactions needed for corolla morphogenesis. Defects in GST development in perianth organs result in folding of the corolla tube, and release of mechanical stress by sepal removal restores corolla elongation. Computational modeling shows that the folding occurs because of buckling caused by mechanical stress from friction at the distal side of the corolla. Our results suggest a novel function of GSTs in regulating the physical interaction of floral organs for macroscopic morphogenesis of the corolla.
