摘要：
The synthesis of metalloporphyrazines with enhanced yields directly from substituted maleonitriles is described. The one-step procedure involves tetramerization using hexamethyldisilazane, p-toluenesulfonic acid and DMF in a sealed tube under microwave irradiation. The reaction time has been drastically reduced from 24 h by classical oil-bath heating to just 15 min. (c) 2007 Elsevier Ltd. All rights reserved.
