Synthesis, characterisation and complexation of di- and trifunctional hybrid ferrocenylphosphine ligands.

2020

Organometallic compounds with at least one metal-carbon bond are used in various fields of chemistry: for example, in medical research for anticancer treatments, in catalytic reactions as catalysts or ligands, in electrochemistry for their redox potentials, in materials chemistry for their optical and electronic properties. The principal family of organometallic compounds of this thesis is ferrocene due to its physical and chemical properties particularly its robustness and the possibility of multiple substitutions on cyclopentadienyl ligands, the dissymmetric functionalization of these cyclopentadienyl rings being a major challenge.The first part of this thesis describes the bibliography o…

Synthèse de pinces à fluorures dérivées d'aminoacides pour l'imagerie TEP

2014

This thesis project, which is part of a collaboration between the Institut de Chimie Moléculaire de l’Université de Bourgogne and the Positron Emission Tomography Research Centre, is about the synthesis of fluoride pincers derived from amino acids based on 18F-B bond construction to get a new class of PET imaging agents. First, this project concerned the design, synthesis and characterisation of new boronato and trifluoroborato phosphonium amino acid salts. Quaternisation of o-boronate phenyl phosphine with β-iodo amino esters or γ-iodo amino ester leads to the corresponding salts without racemisation and in yields up to 88%. Saponification of boronato phosphonium amino esters afford the fr…

TAURINE SUPPLEMENTATION PREVENTS HYPERAMINOACIDEMIA IN GROWING TERM INFANTS FED HIGH PROTEIN COW'S MILK FORMULA. † 1891

1996

Blood urea nitrogen (BUN) and plasma and urine amino acid concentrations were compared between three cohorts of healthy term infants who were breast-fed (BF) or randomly assigned to one of two formulas either taurine non-supplemented (FF) or taurine supplemented (FF+T). The formulas had a protein concentration of 2 g/dl (2.9 g/100 kcal) and a whey/casein ratio of 20/80. The infants were studied from 2 to 12 weeks of age. Weight gain and growth in length was normal and similar in all three feeding groups during the study interval. At 12 weeks BUN was significantly higher in the FF group than in the BF and FF+T groups of infants, 16.5 mg/dl vs 7.0 and 7.3 mg/dl respectively. Total plasma amin…
