Lauryldimethylamine oxide Lauryldimethylamine oxide Lauryldimethylamine oxide (LDAO), also known as dodecyldimethylamine oxide (DDAO), is an amine oxide based nonionic surfactant, with a C (dodecyl) alkyl tail. It is one of the most frequently-used surfactants of this type. Like other amine oxide based surfactants it is antimicrobial, being effective against common bacteria such as "S. aureus" and "E. coli", however it is also non-denaturing and may be used to solubilize proteins. At high concentrations, DDAO forms liquid crystalline phases. Despite having only one polar atom that is able to interact with water – the oxygen atom (the quaternary nitrogen atom is hidden from
Dihydrogen complex variety of related complexes such as Cr(H)(CO) and [Fe(H)(H)(dppe)]. Kubas et al.'s findings also led to a reevaluation of previously described compounds. For example, the complex "RuH(PPh)" described in 1968 was reformulated as a dihydrogen complex. Dihydrogen complex Dihydrogen complexes are coordination complexes containing intact H as a ligand. The prototypical complex is W(CO)(PCy)(H). This class of compounds represent intermediates in metal-catalyzed reactions involving hydrogen. Hundreds of dihydrogen complexes have been reported. Most examples are cationic transition metals complexes with octahedral geometry. Upon complexation, the H−H bond is extended to 0.81–0.82 Å as indicated by neutron diffraction, about a 10%
