The carbornethoxylation was greatly influenced by the variation of temperature and CO pressure. The increase of temperature increased the EO conversion, but decreased the selectivity to MHP. On the contrary, both the yield and the selectivity of MHP increased with increasing CO pressure. FT-IR spectroscopic studies show that Co-2(CO)(8) interacts with (C5H5N)(2)ZnBr2, affording a new ionic cobalt carbonyl species. (c) 2005 Elsevier B.V. All rights reserved.
