Journal ArticleDOI
Synthesis and decarboxylative Wittig reaction of difluoromethylene phosphobetaine.
TL;DR: A key intermediate, difluoromethylene phosphobetaine, in the Wittig reaction of ClCF2CO2Na-Ph3P with aldehydes was synthesized and characterized, which confirmed the reaction mechanism.
Journal ArticleDOI
Equiangular hexagon-shape-controlled synthesis of graphene on copper surface.

TL;DR: A growth model is proposed that qualitatively establishes a connection between various experimental conditions and the grown graphene, and is in principle capable of predicting the results from different conditions in the Cu-methane CVD system.
Journal ArticleDOI
Production of Graphite Chloride and Bromide Using Microwave Sparks
TL;DR: A third chemical approach for the synthesis of large quantities of highly modified graphite which uses a microwave-sparks-assisted halogenation reaction and resulted in device performances which were comparable to, or even better than, that of graphene oxide.
Journal ArticleDOI
Conversion between Difluorocarbene and Difluoromethylene Ylide
TL;DR: The Wittig difluoro-olefination anddifluorocyclopropanation could be selectively realized by using the same reagent, as the ylides obtained from different carbene sources showed different reactivity in Wittig reactions.
Journal ArticleDOI
High‐Performance Phototransistors Based on Organic Microribbons Prepared by a Solution Self‐Assembly Process
