119 The Vilsmeier and Reimer-Tiemann formylation reactions are the subjects of other chapters (Volume 2, Chapters 3.4 and 3.5). Formylation of benzene and simple alkylbenzenes can be achieved in good yields using carbon monoxide, hydrogen chloride and aluminum chloride at high pressures (1–2.5 ...
This reaction has been improved by use of a slightly hydrated solid-liquid medium. This reaction has been applied for the formylation of electron-rich aromatic compounds. Keywords: electronrich aromatic compounds; aromatic aldehydes; ρ-hydroxybenzaldehyde; 3-chloropyridine...
Formylation of phenol in weakly hydrated heterogeneous solid-liquid medium makes it possible to transform phenol into salicyl-aldehyde and parahydroxybenzaldehyde with a ratio of 4.5/1 with excellent yield. Use of methanol as cosolvent modifies the orientation of this reaction, which leads for the ...
To demonstrate the precise temperature control provided by this method, the thermal optimisation of the Riemer-Tiemann formylation of 尾-naphthol was performed under hydrodynamic pumping regimes.Robin ForttAlexander IlesAndrew de MelloInternational conference on miniaturized chemical and biochemical analysis ...
