A facile synthesis of mesoporous graphitic carbon nitride supported palladium nanoparticles as highly effective and reusable catalysts for Stille coupling reactions under mild conditions

Abstract

This paper reports a facile one-pot synthesis of mesoporous graphitic carbon nitride (mpg-CN) supported Pd NPs, denoted as mpg-CN/Pd, as highly efficient catalysts for Stille C–C coupling reactions under mild conditions.

Catalytic dehydrogenation of natural terpenes via CuPd alloy nanoparticles generated on mesoporous graphitic carbon nitride

“…[23] In our recent studies, we have shown that m-gCN could serve both as a stabilizing agent and support material in the wet-chemical synthesis of monometallic Pd and Pt NPs. [21,23,24] In these studies, we also verified that m-gCN could control the particle size of yielded NPs through its nitrogen rich sites, which are located between tri-striazine units of the m-gCN. [25] Moreover, this type of synthesis protocol provides the generation of relatively naked metal NPs surface compared to the surfactantassistant protocols because m-gCN serves as both support and stabilizer in the protocol.…”

Synergism between few-layer black phosphorus and graphitic carbon nitride enhances the photoredox C–H arylation under visible light irradiation

“…76 According to literature, 77 the amount of FLBP in DMF was calculated as about 0.2 mg mL −1 using the methodology above. Following this, the FLBP/g-CN heterojunctions with different FLBP contents were prepared in 5,17,22,30,35,45, and 50 wt% ratios, therefore; the prepared heterojunctions were abbreviated as FLBP 0.05 /g-CN, FLBP 0.17 /g-CN, FLBP 0.22 /g-CN, FLBP 0.30 /g-CN, FLBP 0.35 /g-CN, FLBP 0.45 /g-CN, and FLBP 0.50 /g-CN, respectively. A prepared FLBP/g-CN heterojunction was separated from DMF by centrifugation, washed twice with ethanol, and dried overnight in a vacuum oven at 40 °C.…”

“…20 The formation of heterojunction is one of the most effective ways to enhance the photocatalytic activity of semiconductor materials via promoting electron and hole charge separation. 21 In this regard, many g-CN-based heterojunctions have been reported with metals, 22 metal alloys, 23 metal oxides, 24 multi-component oxides, 25 metal chalcogenides, 26 carbon-based polymers, 27 and carbon-based semiconductors. 28 Among these, metal-free g-CN heterojunctions utilizing only earth-abundant elements play a crucial role in maximizing sustainability.…”

Divergent Synthesis and Semiconductor Properties of Dithienobenzothiazoles with S•••N and S•••S Interactions Controlling Molecular Arrangement in Crystal

“…According to procedures shown in Scheme 1, a common intermediate for divergent syntheses of 1a-g, 5,8dibromo-2-(5-bromothiophen-2-yl)dithieno[2',3':3,4;3'',2'':5,6]benzo [1,2-d]thiazole (5), was prepared from 2,4,5tribromothiazole [31] (2). The Stille cross-coupling reaction of 2 and 2-(tri(n-butyl)stannyl)thiophene [32] with a palladium catalyst provided 2,4,5-tris(thiophen-2-yl)thiazole (3) in 80% yield. [33]…”
