report on a new method for the synthesis of amidesusing acyl pyrazoles and nitroarenes under reducing conditions. It was found that acyl pyrazoles react with organo-nitro compounds in the presence of B2(OH)4, giving the corresponding amides in good yields. We demonstrated that benzoyl pyrazoles having various substituents and nitroarenes with different substituents can be used to produce a range of N-substituted
Embodiments relate to lubricants disposed over magnetic storage media, such as rotatable thin film magnetic discs. One embodiment comprises a lubricant compound of a fluoropolyether chain having one or more carbonyl-imide pairs. For example, the carbonyl-imide pair may be located at one end, both ends, and/or in the middle of the fluoropolyether chain.
