General description

The orthorhombic nature of copper hydroxide crystals was determined by X ray diffraction. Copper hydroxide can act as a heterogeneous catalyst in the selective oxidative cross coupling of terminal alkynes to yield their corresponding ynamides.

Application

Copper hydroxide based monoliths can be used in the synthesis of copper hydroxide-based monolithic xerogels. Potential applications of this metal organic frameworks (MOFs) include gas storage, separation, drug delivery, and biomedicine. Supported Cu(OH)x can be used as a catalyst for the aerobic cross dehydrogenative coupling of benzenethiols and cyclic amides to yield N-acylsulfenamides.
