mechanochemistry: a force of synthesis | acs central science

dec 29 2016· the past decade has seen a reawakening of solid-state approaches to chemical synthesis driven by the search for new cleaner synthetic methodologies. mechanochemistry i.e. chemical transformations initiated or sustained by mechanical force has been advancing particularly rapidly from a laboratory curiosity to a widely applicable technique that not only enables a cleaner …

reaction under ball-milling: solvent- ligand- and metal ...

oct 11 2013· a convenient efficient and general procedure for the synthesis of diaryl chalcogenides including sulfides selenides and tellurides has been developed by the reaction of diazonium tetrafluoroborates and diaryl dichalcogenides on the surface of alumina under ball-milling without any solvent or metal. a wide range of functionalized diaryl chalcogenides are obtained in high purity by this ...

organic & biomolecular chemistry

through ball-milling.5 it is also known that solid-state syn-thesis by ball-milling can enable (water and/or oxygen) sensi-tive reactions to be more reliably carried-out.6 this is particu-larly attractive not only from the view-point of increased repro-ducibility but also from the stance of reduced effort and
