Two novel crown ether compounds, N,N′-bis(2-hydroxy-5-nitrobenzyl)-4,13-diazadibenzo-18-crown-6 (CCE) and N,N′-bis(7-hydroxy-4-methylcoumarin-8-methylene)-4,13-diazadibenzo-18- crown-6 (FCE), have been synthesized as potential reagents for the selective e

A series of arylstannanes have been synthesized, through an SRN1 mechanism, in good to excellent yields (74%-99%) by the photostimulated reaction of trimethyl stannyl ion with substrates supporting different nucleofugal groups. The arylstannanes thus obtained were suitable intermediates for Stille cross-coupling reactions leading to asymmetric bi- and triaryl compounds in acceptable global yields. An attractive feature of this route is that simple commercially available benzenediols, chloro- and methoxy phenols might be useful starting substrates, leading the latter to higher global yields of products in fewer steps. The strategies proposed open a broad synthetic tool.
