Thin-gold films have been laid down on the inner surface of borosilicate capillaries using a variety of deposition techniques and the resultant film composition and morphology has been evaluated using energy-dispersive x-ray (EDX) and scanning electron microscopy (SEM) analysis, respectively. These films have been shown to couple very strongly with microwave irradiation to generate very high temperatures (>850 °C). These films have been demonstrated to be highly reactive catalytically in a number of mechanistically-diverse chemical transformations. Wide selections of structurally-varied compounds have been made by hydrosilylation, benzannulation, and alkyne additions to imines.
