   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phosphorus chemistry; H-phosphonate; H-phosphonoselenoate; nucleotide analogues; selenization; selenium transfer; phosphoroselenoate; Organic chemistry; Organisk kemi;

   Sammanfattning : In this thesis, the chemistry of compounds containing P-Se bonds has been studied. As a new addition to this class of compounds, H-phosphonoselenoate monoesters, have been introduced and two synthetic pathways for their preparation have been developed. LÄS MER

3. 2. Expanding the H-phosphonate and H-phosphonothioate chemistry towards biologically important phosphate analogs

   Författare :Gaston Lavén; Jacek Stawinski; Wojciech T. Markiewicz; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phosphonate; phosphonothioate; H-phosphonate; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

   Sammanfattning : This thesis focuses on chemical transformations of H-phosphonate and H-phosphonothioate and can be divided in two parts. The first part, is devoted to the development of the palladium-catalyzed P-C bond formation. Both mechanistic and synthetic studies of the transformations have been performed. LÄS MER
