Triethylamine is now employed extensively as a base. Recently, it has been used for an improved prepn. of hydrazones and their conversion into em-diiodides and a,/ -ethyleneiodides A number of condensations, e.g. the prepn. of 4-hydroxycoumarins from phenols, can be performed under mild conditions with a mixture of zinc chloride and phosphorus oxide chloride One of the most frequently used media, dimethylformamide, is still extending its range of applications. Recently, it has been used successfully for ring closures, e.g. to purine derivatives and for various kinds of reactions with methyl iodide in the presence of silver or barium oxides...
