The Preparation and 13C-NMR Spectra of Alkoxymethyl-triphenylphosphonium Salts

Alkoxymethyltriphenylphosphonium salts, X, X: Cl, Br, and I, R: CH3, C2H5, and i-C3H7, have been obtained from the reaction of the triphenylphosphine and the corresponding alkyl halomethyl ether.In the 13C-NMR spectra of these salts, the coupling constant (JCP) is 68-71 Hz, which is larger than that (JCP: 48-56 Hz) of Br,R:H,CH3, and i-C3H7, Me3P=S and Me3P=Se, while it is close to that(66-69Hz) of Me3P=O and Et3P=O.The coupling constant (JCP) of these salts can be caused by the oxygen atom in the salts.

Visible Light Induced Cyclization to Spirobi[indene] Skeletons from Functionalized Alkylidienecyclopropanes

In this paper, we revealed a metal-free and visible light photoinduced method for the rapid construction of spirobi[indene] skeletons, providing a simple and efficient way for easy access to spirobi[indene] scaffolds under mild conditions along with a broad substrate scope and good functional group tolerance.
