1. 1. Novel Pincer Complex-Catalyzed Transformations : Including Asymmetric Catalysis

   Författare :Juhanes Aydin; Kálmán J. Szabó; Oleg V. Ozerov; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pincer; palladium; catalysis; chiral; asymmetric; palladium IV; allylation; aldol; aminoacid; C-H functionalization; cross-coupling; homoallylic; heck reaction; tridentate ligand; Chemistry; Kemi; Organic Chemistry; organisk kemi;

   Sammanfattning : This thesis is focused on the development of new pincer complex-catalyzed transformations. Optimization of the catalytic properties (fine-tuning) was directed to increase the catalytic activity as well as the chemo-, stereo- and enantioselectivity of the complexes. LÄS MER

3. 2. Catalytic Functionalization of Allylic Substrates by Palladium Pincer Complexes

   Författare :Nicklas Selander; Kálmán Szabó; David Milstein; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Catalysis; Palladium; Pincer Complex; Boron; Multicomponent Reaction; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

   Sammanfattning : This thesis is based on the development of novel catalytic reactions for the synthesis and application of organometallic reagents. The main focus is directed towards organoboronate derivatives. We developed an efficient procedure for converting allylic alcohols to the corresponding allylboronates using palladium pincer complexes as catalysts. LÄS MER

4. 3. Reactivity of late transition metal complexes towards CO2 and other electrophiles

   Författare :Magnus Johnson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CO2; carbon dioxide; electrophiles; late transition metal complexes; catalysis; halogen bonding; XB; cyclometallation; pincer; organometallic synthesis;

   Sammanfattning : In times when dwindling energy resources is a major long-term problem for sustaining modern infrastructure and technologies, we need to focus on more enduring solutions. A key contribution to this achievement is catalysis. LÄS MER

5. 4. Femoroacetabular impingement syndrome. Trends and outcomes after arthroscopic treatment in the general and athlete population

   Författare :Ida Lindman; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; femoroacetabular impingement syndrome; FAIS; hip arthroscopy; athletes; cam; pincer;

   Sammanfattning : Femoroacetabular impingement syndrome (FAIS) is a common cause of hip pain in the young and athletic population. The diagnosis - FAIS - is based on a triad of symptoms, clinical evaluation and radiographic signs. The impingement is caused by an abnormal morphology of the femoral head (cam) and/or the acetabulum (pincer). LÄS MER

7. 5. High-load injuries in the adolescent athlete's hip; clinical and experimental studies and outcome measures

   Författare :Pall Jonasson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hip; groin; athlete; adolescent; femoroacetabular impingement; cam; pincer; osteoarthritis; porcine; epiphyseal plate; growth; validity; reliability; iHOT; HAGOS;

   Sammanfattning : The diagnosis and treatment of hip and groin symptoms has often been a problem area in orthopaedics and sports medicine. Hip and groin pain and injuries are common among athletes and in the increasingly active population. LÄS MER
