  1. 1. Lowcoordinated Silicon and Hypercoordinated Carbon : Structure and Stability of Silicon Analogs of Alkenes and Carbon Analogs of Silicates

    Författare :Anders M. Eklöf; Henrik Ottosson; Sten Lunell; Thomas Müller; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; silenes; zwitterionic silenes; silenolates; reverse polarization; natural resonance theory; hypervalent carbon; hypercoordinated carbon; thermolysis; lowcoordinated silicon; Organic chemistry; Organisk kemi;

    Sammanfattning : Quantum chemical studies on lowcoordinated group 14-16 compounds have been performed. This thesis focuses particularly on silenes influenced by reverse Siδ-=Cδ+ bond polarization. Hypercoordinated carbon compounds are also studied. LÄS MER

  3. 2. Synthesis and Reactivity Studies of Zwitterionic Silenes and 2-Silenolates

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Silicon; Zwitterionic Silene; 2-Silenolate; Diels-Alder Reaction; Silacyclohexene; X-ray Crystallography; Organisk kemi; Organic chemistry; Organisk kemi;

    Sammanfattning : This thesis describes synthesis and reactivity studies of 2-amino-2-siloxysilenes and 2-silenolates, species that are strongly influenced by reversed Si=C bond polarization, i.e. an Siδ-=Cδ+ polarization as compared to the natural Siδ+=Cδ- polarization. LÄS MER

  4. 3. Low-coordinate Organosilicon Chemistry : Fundamentals, Excursions Outside the Field, and Potential Applications
