in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
In 14 patients undergoing open-heart operations the haemodynamic effects of diazepam 0.4 mgkg(-1) followed by ketamine 2 mg kg(-1) were studied. In eight patients undergoing coronary bypass surgery, the mean arterial pressure decreased significantly after diazepam from 90.3 +/-7.4 (SEM) to 78.0 +/-5.0 mm Hg (P less than 0.05). However, no changes occurred in six patients undergoing valve replac...
