摘要：

Thermal and photolytic reactions of lithium pentacarbonyl(1-oxidoethylidene)chromate-(0) (1) and tetramethylammonium pentacarbonyl(1-oxidoethylidene)chromate(0) (22) with various electron deficient alkenes were investigated. The acyl metalates were found to be formally an acetyl anion equivalent, adding in a Michael fashion. Depending on reaction conditions, the products were found to be derived from the addition of 1 equiv of pentacarbonyl(1-oxidoethylidene)chromate(0) to either 1, 2, or 3 equiv of the initial alkene. Conditions were found affording exclusively or predominantly 1:1 addition and, conversely, 2:1 addition.
