Journal ArticleDOI
Synthesis of selectively trifluoromethylated pyridine derivaties as potential antihypertensives
Robert W. Lang,Paul Wenk +1 more
TL;DR: In this article, a general synthesis of selectively 6-(trifluoromethyl)-substitued 2(1H)-pyridinones is described, which leads to the new CF3-containing potassium-channel openers 2a and 2b.

Substituted benzoylphenylureas compounds useful as pesticides
TL;DR: The N-benzoyl-N,-4-(5-phenylpyrimid-2-yloxy)phenylureas of as discussed by the authors have been used for pest control.
Journal ArticleDOI
Fluorine-containing organozinc reagents. VI, The preparation of α-trifluoromethyl-α,β-unsaturated carboxylic acid esters
TL;DR: The reformatzky reaction of the readily available methyl 2,2-dichloro-3, 3,3,3 trifluoropropionate with aldehydes followed by acylation and reductive elimination in situ constitutes a general synthetic scheme for the preparation of methyl α-trifluorsomethyl-α,β-unsaturated carboxylates, useful as fluorine-containing building blocks.
Journal ArticleDOI
Fluorine‐Containing Organozinc Reagents Part 1 A Simple Synthesis of 2,2‐Dichloro‐3,3,3‐trifluoropropanol
TL;DR: A brief survey of the scope of this CC-bond formation leading to a variety of new CF3-containing synthetic building blocks is also given in this paper, which can be regarded as a synthetic equivalent of substituted 1,1,1-trifluoroacetone 2.
Patent
Production for producing 3-cyano-4-phenyl indoles and intermediates
Pierre Martin,Robert W. Lang +1 more
TL;DR: In this paper, a process for producing fungicidally active 4-phenylpyrrole derivatives of the formula I ##STR1## was described, wherein R is halogen, C1 -C6 -alkyl or C1-C6-haloalkyl, and n is 0, 1 or 2.
