A palladium-catalyzed cascade allylative dicarbofunctionalization of aryl phenol-tethered alkynes with allyl iodides is described. A series of polysubstituted spirocyclo-containing skipped dienes with an all-carbon tetrasubstituted alkene unit are synthesized through this convenient process. The cascade reaction proceeds selectively through dearomative C-allylation instead of O-allylation of aryl phenols.Bi3+/Te4+ co-doped Cs2SnCl6 with dual emission spectrum (i.e., 450 and 575 nm) was achieved by a modified solution method, which can over
