The cluster catalyzed hydration of 1-hexyne to yield 2-hexanone. The catalytic activity increased with increasing temperature, the selectivity for 2-hexanone being 70% in the temperature range 250-400 degrees C. 1-Heptyne, 1-octyne, 1-nonyne, and phenylacetylene were also preferentially hydrated to produce the corresponding ketones. 2-Hexyne provided 2- and 3-hexanones in equal amounts, as happens with Bronsted acid catalysts. Halide clusters of niobium, molybdenum, and tantalum having the same octahedral metal framework were also active catalysts for the reaction.","subitem_description_type":"Abstract"}]},"item_119_description_21":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"The original publication is available at
