Turn-on fluorescence sensor for mono- and di-phosphonic acid derivatives using anthracene-based diamidine and its detection of amidinium-phosphonate and amidinium formation

The fluorescence detection of di-phosphonic acid and mono-phosphonic acid derivatives using the anthracene-based diamidine 1 has been investigated. The diamidine 1 forms 1:1 and 1:2 complexes with the di-phosphonic acid and mono-phosphonic acid derivative

Flexible diphosphonic acids for the isolation of uranyl hybrids with heterometallic UVI = O - ZnII cation-cation interactions

A family of uranyl diphosphonates have been hydrothermally synthesized using various flexible diphosphonic acids and Zn(UO2)(OAc) 4·7H2O in the presence of bipy or phen. Single-crystal X-ray analyses indicate that these compounds represent the first examples of uranyl phosphonates with heterometallic UVI = O - Zn II cation-cation interactions.

Medium-ring diphosphines from diphosphabicycloalkanes: stereoselective syntheses, structure and properties

A series of 1,k+2-diphosphabicycloalkanes 2b-e are prepared by n-BuLi-promoted cyclisation of 1,ω-diphosphinoalkanes, followed by alkylation and cycloalkylation with 1,ω-dihaloalkanes.These compounds appear to be exclusively cis-isomers except 1,6-diphosphabicycloundecane 2e which is a 3:1 cis/trans mixture.Mono-quaternisation of cis-1,k+2-diphosphabicycloalkanes, followed by treatment of the mono-quaternary salts with alkyllithium or Grignard reagents produces cis-1,n-disubstituted-1,n-diphosphacycloalkanes 4 exclusively; examples containing 8-, 9- and 10-membered rings and a range of substituents on phosphorus are described.Di-quaternisation of 1,k+2-diphosphabicycloalkanes, followed by hydrolysis, yields the trans-isomers of 1,n-disubstituted-1,n-diphosphacycloalkane monooxides 6 exclusively; reduction of these with LiAlH4 in benzene gives largely trans-1,n-disubstituted-1,n-diphosphacycloalkanes 7, but is not completely stereoselective.The structure and properties of these diphosphacycloalkanes are discussed.He(I) photoelectron spectra of 1,5-diphosphabicyclooctane, 1,6-diphosphabicyclononane and 1,6-diphosphabicyclodecane show little evidence of interaction between phosphorus lone pairs, unlike the corresponding hydrazines.The medium-ring diphosphacycloalkanes, 1,5-dimethyl-1,5-diphosphacyclooctane and 1,6-dimethyl-1,6-diphosphacyclodecane also show little evidence of interaction between phosphorus lone pairs.
