Phosphorus hydrazides PhP(O)[N(Me)NH2]2, (S)P[N(Me)NH2]3, and N3P3[N(Me)NH2]6 were condensed with 7-diethylaminocoumarin-3-aldehyde (RCHO) to afford the corresponding hydrazones PhP(O)[N(Me)NCHR]2 (1), (S)P[N(Me)NCHR]3 (2), and N3P3[N(Me)NCHR]6 (3). The structural characterization of 1–3 was carried out by their HRMS, 1H and 31P1H} NMR spectra. The molecular structure of 2 was established by a single-crystal
2,2′ disubstituted phosphonothioic or phosphonic dihydrazides 3a-p or 3a′-g′ and 2,2′,2″ trisubstituted phosphonothioic or phosphonic trihydrazides 4a-e, 4i-l or 4a′-h′ were prepared in high yields by reacting phosphonothioic or phosphonic di- or trihydrazides 1a,a′,b or 2a,a′ with various aldehydes. The structure of one of these compounds 4a′ was solved by X-ray analysis.
afforded another type of bimacrocyclic species, 20, containing five phosphorus atoms. A Staudinger reaction between the phosphine 22 bearing a crownetherunit and the diazido tetraphosphorus-containing macrocycle 21 led to a trimacrocycle, 24, possessing one central phosphorus macrocycle and twocrownethers. Similarly the reaction between phosphine 22 (4 equiv) with the tetraazido tetraphosphorus-containing
