Catalytic Cyclocarbonylation in Compressed Carbon Dioxide: Pressure Influence of Carbon Monoxide and Carbon Dioxide

Among the current interests in organic synthesis are those reactions performing multiple C-C bond formation, in special when they undergo under catalytic conditions. Due to its properties, there is a growing interest on the use of compressed fluids (CF) as solvent media in catalytic processes. In this context, we present herein studies that aim to the development of a cleaner technology for the...

Carbon Dioxide, Narcosis, and Diving

Carbon dioxide (CO2) is the gaseous end product of the aerobic metabolism of oxygen. CO2 is highly soluble in body tissues, and readily diffuses from cells to blood, where circulation transports it to the lungs for elimination. Divers often ignore carbon dioxide, as CO2 is a normal part of life. However, CO2 may have definite and detrimental effects if a diver accumulates an excessive amount of...

Coral reefs and carbon dioxide.

ated with transitions to benthic communities dominated by noncalcareous benthos (4, 8). The results of Kayanne et al. (1) reveal metabolic measures to be sensitive indicators of reef health (9), but the findings more likely reflect the condition of the local sampling site than the normal behavior of healthy reef communities.
