convenient preparation, handling and purification by distillation. They are highly reactive compounds that have been found to be suitable precursors for vapor deposition of cobalt metal, cobalt nitride and cobalt oxide. A new synthetic method allows for the facile and inexpensive preparation of large quantities of these compounds.
制备了三种新的挥发性a基钴化合物:Co(t BuNC(R)NEt)2,R = Me,Et和n-Bu。他们的特点是元素分析, 1 H NMR,X射线结构分析,熔点,蒸气压,汽化速率,热稳定性和化学反应性。发现它们干净蒸发,没有分解。其中两种在室温下为液体,可以更方便地进行制备,处理和纯化 经过 蒸馏。它们是高反应性的化合物,已经发现它们是用于钴金属,氮化钴和氧化钴的气相沉积的合适前体。一种新的合成方法使得可以方便且廉价地制备大量这些化合物。
