The Cl replacement reactions of N/N or N/O spirocyclic monoferrocenylcyclotriphosphazatrienes (1-5) with the piperidine resulted in the geminal-(6-10) and tetra-piperidinophosphazenes with monoferrocenyl pendant arm (11-15). The structures of all the new compounds were determined using spectroscopic techniques. The ultrathin Langmuir-Blodgett (LB) films of two compounds (3 and 12) were prepared. The characterization of the LB films using p-polarized grazing angle (GAIR) and horizontal attenuated total reflectance (HATR) techniques was carried out. The molecular and crystal structure of the compound 6 was examined using X-ray crystallography. In addition, the interactions between six compounds (6, 7, 11, 12, 14 and 15) and pBR322 plasmid DNA were investigated by agarose gel electrophoresis.
Oxidative cyclizations of oxopropanenitriles with diphenylalkenes or phenyl(thienyl)alkenes are comparatively studied. As a result, the thienyl--substituted alkenes afford higher yields of title furancarbonitriles than diphenylalkenes (II) and (IV). -(YILMAZ*, M.; UZUNALIOGLU, N.; PEKEL, A.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
