    Abstract : Popular Abstract in Swedish En ny typ av vattenlösliga fosfin ligander har utvecklats. Dessa fosfiner har använts som ligander i rhodium katalyserade tvåfasreaktioner.Komplexbildningen mellan de nya liganderna och olika metalcentra har studerats och de nya komplexen har använts i hydroformylerings- och hydreringsreaktioner.

    Abstract : Popular Abstract in Swedish Utvecklingen av säkrare och mer miljövänliga processer är en av de största utmaningarna som den kemiska industrin står inför. I det här sammanhanget är katalys i tvåfassystem, bestående av vatten och organiska lösningsmedel, av största intresse eftersom den möjliggör en enkel återvinning av katalysatorn samtidigt som den minskar skadliga utsläpp och kostnader för återvinning av lösningsmedlet.
