11. C–H and Si–H functionalization using redox-active diazo compounds and decarboxylative coupling
Sammanfattning : The work presented in this thesis is based on two basic organic chemistry concepts: carbene catalysis and radical coupling reactions. Diazo compounds in the presence of transition-metal catalysts are known to be excellent reagents for the construction of C–X bonds (X = C, Si, N, O, etc.) under mild conditions. LÄS MER
12. Asymmetric Synthesis using Redox-Active Diazocompounds as Chiral Carbon Atom Precursors
Sammanfattning : This thesis summarizes the development of general and efficient methods to synthesize enantiomerically enriched cyclopropane compounds. The works reported herein exploit the opportunity presented by redox-active esters to explore the orthogonality between asymmetric carbene-transfer and geminal radical generation. LÄS MER
13. Development of Novel Hydroporphyrins for Light Harvesting and Sensitising NIR Lanthanide Luminescence
Sammanfattning : Chlorins, as the core structures of chlorophylls, have been extensively studied for harvesting solar energy, fluorescent imaging and photodynamic therapy against cancer. This thesis is concerned with design and synthesis of novel chlorins as antennae for harvesting light and sensitising near infrared lanthanide luminescence. LÄS MER
