摘要: Cyclic acetal derivative of a resole includes the reaction product of an ortho resole compound with a carbonyl compound or a carbonyl compound derivative. The cyclic acetal derivatives of phenolic resole compounds exhibit enhanced storage stability and can be readily activated at elevated temperatures to prepare phenolic based adhesives and coatings.

摘要: A process is provided whereby organic carbonyl substrates, including esters, ketones and amides, are reduced in a reaction with a silane reducing reagent and a catalyst. Effective catalysts broadly include those which consist of a group 4, 5 or 6 metal which either: a) is in less than its maximum oxidation state or is capable of being converted to a complex in less than its maximum oxidation state; and/or is a group 4, 5 or 6 metal hydride. Exemplary catalysts include titanium-containing catalysts such as (bis trimethylphosphine) titanocene, trimethyl phosphine adduct of a (hydrido) silyl complex of titanocene, titanocene dichloride and titanocene monochloride.
