摘要

The reaction of lithium trimethoxyaluminum hydride with 0.5 molar equiv of cuprous bromide produces a heterogeneous mixture referred to as the Li complex, while sodium bis (2- methoxyethoxy) aluminum hydride with 1.0 molar equiv of cuprous bromide gives a similar mixture, the N a complex. Both reagents are effective in selective reduction of the olefin unit in conjugated ketones and esters, including two examples of acetylenic esters. The Li ...
