Article abstract of DOI:10.1016/S0040-4039(00)71512-7

The title compound selectively reduces acid chlorides to aldehydes under neutral conditions and aldehydes and ketones to alcohols in acidic media. 4-tert-Butylcyclohexanone is reduced to the trans alcohol with a high degree of stereoselectivity (94:6).
