- Reduction of Carboxylic Acid with 2-Propanol over Hydrous Zirconium Oxide
-
The vapor-phase reduction of carboxylic acids with 2-propanol was found to proceed efficiently over hydrous zirconium(IV) oxide, and the corresponding alcohols were obtained in high yield.Esters were also reduced.

- Synthesis and Properties of a Series of Sterically Hindered Guanidine Bases
-
By the reaction of Vilsmeier salts, derived from tetra-alkylureas or from tetra-alkylthioureas, with primary aliphatic amines, a series of sterically hindered penta-alkyl guanidines has been prepared. 2-t-Butyl-1',1',3'',3''-tetramethylguanidine and pentaisopropylguanidine combine ease of preparation with a range of resistance to alkylating agents.Preliminary experiments indicate that these inexpensive bases will useful in organic synthesis.
