Zeolite Y nanosheets with a micro-meso-macroporous structure were synthesized, and applied in the assembly of a Pd catalyst (Pd/NS-Y) for direct vinylation of thiophenes with high activity and selectivity, as compared to Pd(OAc)2, Pd(NO3)2, and Pd(PPh3)4 catalysts. This feature should be assigned to the highly dispersed Pdδ+ (δ 2+.
Thioketones and Enethiolates by 1,3-Anionic Cycloreversion of Dithiolane Derivatives

The reactive (ar)aliphatic thioketones 3a-c are generated by cycloreversion of the anions 2 of 1,3-dithiolane-4,5-dicarboxylates 1 and are trapped by mesitonitrile oxide (5) in a 1,3-dipolar cycloaddition to give 7.From the fragmentation of anions 12 of 1,3-dithiolane 1,1-dioxides 11, thiobenzophenone (3d) and thiocamphor (3e) are isolated, wheras thioketones 3a,c with α-hydrogen are deprotonated in situ to provide enethiolates 13.Anions 13 add nitrile oxide 5 to yield thiohydroximates 8.
