This book aims to open new fields of interest in phosphate chemistry and to suggest a new system of classification for phosphates. Due to the very rapid development of this branch of chemistry during the last thirty years and the very confusing nomen

We report herein the synthesis and the X-ray crystal structure of 2-azido-2-deoxy-3,4-O-isopropylidene-α-d-galactopyranosyl-N-oxyphthalimide 3 which is the key-precursor of a cancer-related STn antigen analogue 5. Compound 3 crystallizes from a mixt

To develop new 99mTc-labelled agents to evaluate dopamine transporters (DAT) involved in Parkinson's disease, by in vivo SPECT imaging, we have synthesized six new sulfur-containing ligands with the tropane skeleton. We have introduced the complexing

New dissymmetric tertiary amines (N(3)SR) with varying N/S donor sets have been synthesized to provide mono- and dinuclear complexes. Acetate ions are used to complete the octahedral coordination sphere around nickel(II) atom(s). The facile conversio

The synthesis of P-N-P bidentate ligands and the evaluation, based on IR and X-ray data, of their pi-acceptor properties in the complexes derived from phenylacetylene-dicobalt hexacarbonyl have been carried out. In addition, the reactivity of these c

The novel C2 symmetric chiral amine trans-2,6-dimethyl-2,6-diphenylpiperidine has been synthesized via two successive nitrone nucleophilic addition-oxidation sequences, followed by reduction of the intermediate nitroxide. Pure enantiomers have been o

The trans stereochemical relationship of the two substituents of the title compound, C9H12N2O5, a new spiro-nucleoside, has been confirmed. The cyclopentane moiety adopts the C3′-endo-type conformation, while the barbiturate ring is almost planar

As in all previously investigated adducts of telluric acid with monovalent inorganic or organic cation phosphates, the phosphoric anions (here P 8 O 24 rings) and the Te(OH) 6 groups coexist as independent entities inside the atomic arrangement. In a

The phase equilibrium diagram has been established by DTA. PbRb(PO 3 ) 3 , the only intermediated compound observed in this system, is a long-chain polyphosphate. This salt is monoclinic, P2 1 /n, with Z=8 and the following unit-cell dimensions: a=14

Among the various condensation schemes occurring in phosphoric anions one of them leads to the formation of cyclic entities. The corresponding salts, for a long time called “metaphosphates” are now denominated cyclophosphates. Built up by a ring
