Cadmium perchlorate hydrate

Jeong et al. reported cadmium perchlorate hydrate [CdlClOja xHjO] as a novel, expeditious catalyst for the three-component synthesis of a-amino-phosphonates via a one-pot reaction of an amine, a carbonyl (aldehyde/ ketone) and a H-phosphonate diester e.g. dimethylphosphite/diethylphos-phite) in open air in the absence of any solvent, with high yields (Scheme 17.15). This new methodology is the first example of a cadmium perchlorate hydrate-catalysed Kabachnik-Fields reaction. ...
