Description

General description

The bacterial mutagenecity of 1-pentene was studied.

Application

1-Pentene was used to develop a rhodium/xantphos homogeneous catalyst system for direct chemo- and regioselective mono-N-alkylation of primary amides with 1-alkenes.

Amylenes do not lead to bacterial mutagenicity in contrast to structurally related epoxides.

Götz A Westphal et al.

BioMed research international, 2014, 592434-592434 (2014-02-11)

Amylenes are unsaturated hydrocarbons (C5H10), such as 1-pentene, 2-pentene, 2-methyl-but-1-en (3-methyl-1-butene), 2-methyl-but-2-en (isopentene), and 3-methyl-but-1-en. We investigated bacterial mutagenicity of 1-pentene, 2-pentene, and 3-methyl-but-1-en in the Ames test. 2-Pentene was investigated as racemate and as pure diastereomers. We included the

Chemo- and regioselective homogeneous rhodium-catalyzed hydroamidomethylation of terminal alkenes to N-alkylamides.

Saeed Raoufmoghaddam et al.

ChemSusChem, 6(9), 1759-1773 (2013-09-07)

A rhodium/xantphos homogeneous catalyst system has been developed for direct chemo- and regioselective mono-N-alkylation of primary amides with 1-alkenes and syngas through catalytic hydroamidomethylation with 1-pentene and acetamide as model substrates. For appropriate catalyst performance, it appears to be essential

13C and 2H kinetic isotope effects and the mechanism of bromination of 1-pentene under synthetic conditions.

S R Merrigan et al.

Organic letters, 1(2), 327-329 (2000-05-24)

[formula: see text] The 13C and 2H kinetic isotope effects for the bromination of 1-pentene with Br2 in CCl4 were determined and interpreted with the aid of calculationally predicted isotope effects. The isotope effects observed are consistent with rate-limiting bromonium
