Prins reactionn.

Brit.

/ˈprɪns rɪˌakʃn/, U.S.

/ˈprɪns riˌækʃ(ə)n/

Origin: From a proper name, combined with an English element. Etymons: proper name Prins , reaction n.

Etymology: < the name of Hendrik J. Prins (1889–1958), Dutch chemist, who described the reaction in Chem. Weekblad (1917) 14 932 and subsequent papers published in 1919 and 1920 + reaction n.

Chemistry.

An addition reaction between an alkene and an aldehyde in the presence of an acid catalyst, yielding a 1,3-diol, an allyl alcohol, or a 1,3-dioxan, depending on the particular reactants and conditions used.

1944 Jrnl. Chem. Soc. 296 Under the conditions of the Prins reaction, a normal, acid-catalysed addition to the olefinic linking occurs.

1974 Jrnl. Chem. Soc.: Chem. Commun. 4 151 In this series of steps, the starting stage was the Prins reaction of norbornadiene and paraformaldehyde in formic acid.

2003 Chemistry & Industry (Nexis) 17 Feb. 26 The route continues by building a substrate (2) for an oxy-anionic Cope rearrangement, followed by an intramolecular Prins reaction.
