Abstract
Background: 2,2-Disubstituted-1,3-dicarbonyls, including iodonium ylides, indanedioneketene precursors, sulfur ylides, 2,2-difluoro-1,3-diketones, 2,2-dihydroxyl- 1,3-diketones and cyclopropyl 1,3-dicarbonyls, are important intermediates in organic synthesis.
Methodology: They are used in the preparation of various amides, benzofurans, furanones, quinones, and so on. However, there is no review to summarize their multiperformance and fundamental mechanisms.
Conclusion: This review will focus on recent applications of 2,2-disubstituted-1,3- dicarbonyls mainly based on three reactivity patterns, which may enlighten the further research.
Keywords: Iodonium ylides, indanedioneketene precursors, sulfur ylides, difluoro, dihydroxyl, cyclopropyl, mechanism.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
