Non-catalytic conversion of C–F bonds of gem-difluoromethylene derivatives to C–H bonds with lithium aluminum hydride under room temperature
摘要:
An unexpected hydrodefluorination of unactivated aliphatic C-F bonds of CF2 derivatives with LiAlH4 at room temperature without any added metal catalyst was reported. Deuterium-labeling experiments suggested that the hydrogens introduced into the products originated from LiAlH4. (C) 2010 Elsevier Ltd. All rights reserved.
