Oxygenation vs iodonio substitution during the reactions of alkenyl-silanes with iodosylbenzene: participation of the internal oxy group.
نویسندگان
چکیده
Reaction of 4-acyl-oxy-but-1-enyl-silanes with iodosylbenzene in the presence of BF(3) x OEt(2) gave 4-acyloxy-2-oxobutyl-silane and 3-acyloxy-tetrahydrofuran-2-yl-silane via a 1,3-di-oxan-2-yl cation intermediate, which is generated by participation of the acyloxy group during the electrophilic addition of iodine(III) to the substrate.

متن کاملEffects of Pentoxifylline on Oxygenation and Exercise Tolerance in Patients with Severe Chronic Obstructive Pulmonary Disease
Background: It was hypothesized that the use of Pentoxifylline would increase arterial O2 saturation and increase exercise tolerance in patients with Chronic Obstructive Pulmonary Disease (COPD). Methods: We tested this hypothesis in 23 patients with COPD and pulmonary hypertension. Patients were randomized to receive Pentoxifylline or placebo, each for a 12-week period, in a prospectiv...
متن کاملBlood oxygenation during hyperpressure intraperitoneal fluid administration in a rabbit model of severe liver injury: Evaluation of a novel concept for control of pre-hospital liver bleeding
Oxygen is an essential part of the most important metabolic pathways in aerobic organisms. Oxygen delivery is merely dependent on blood, rendering blood loss a devastating event. Traumatic pre-hospital liver bleeding is a major cause of early trauma deaths in human and animals, with no established therapeutic method yet. Increasing intra-abdominal pressure (IAP) has been shown to reduce liver b...

Bifunctional silanes constitute valuable linking agents for attachment of biomolecules at high levels of surface population density through the formation of thioether or disulfide bonds. Three such compounds, 1-((trifluoroacetyl)-thio)-11-(trichlorosilyl)undecane, 1-bromo-11-(trichlorosilyl)undecane, and 1-((bromoacetyl)oxy)-11-(trichlorosilyl)undecane, are discussed in terms of their surface c...
