The reactivity of diphenylgermylene (Ph2Ge) with several classes of germylene scavengers has been studied in hexane solution at 23 degrees C by laser flash photolysis of 3,4-dimethyl-1,1-diphenyl-1-germacyclopent-3-ene (1a), a clean and highly efficient precursor to the germylene and its dimer, tetraphenyldigermene (2a). The reactions studied include M-H insertion reactions with Group 14 hydrid...

A fundamental understanding of surfactant structure–property–performance relationships will inform the design next-generation alternatives to perfluoroalkyl substances (PFAS) in aqueous film-forming foams. This manuscript describes synthesis, solution properties, and foam stability novel triethylsilyl-containing surfactants, which elucidated influence hydrophilic head group on critical micelle ...

Time-resolved kinetic studies of the reaction of dimethylsilylene, SiMe2, generated by laser flash photolysis of 1,1-dimethyl-1-silacyclopent-3-ene, have been carried out to obtain rate coefficients for its bimolecular reactions with trimethylsilane-1-d, Me3SiD. The reaction was studied in the gas phase at five temperatures in the range 292-605 K. The rate coefficients showed no pressure depend...

The metabolism and excretion of ziprasidone (5-[2-{4-(1,2benzisothiazol-3-yl)piperazin-1-yl}ethyl]-6-chloroindolin-2-one hydrochloride hydrate) were studied in Long Evans rats after oral administration of a single dose of a mixture of Cand H-labeled ziprasidone. The radioactive dose was quantitatively recovered over 7 days in both male and female rats. The percentage of the dose excreted in uri...
