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.

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.
The Synthesis and Properties of a Series of Strong but Hindered Organic Bases
Barton, Derek H. R.,Elliott, John D.,Gero, Stephen D.
, p. 1136 - 1137 (2007/10/02)
A series of highly hindered N1,N2,N2,N3,N3-penta-alkylguanidines has been synthesised from inexpensive starting materials; these strong bases show interesting effects in organic synthesis.
