Substituted cinnamic oxime and hydroxamide derivatives

A process for reducing the level of tri-substituted phosphine, arsine and/or stibine oxide from a mixture comprising a desired product and at least one such oxide is provided, comprising the addition of a metal salt to the mixture to form a complex with the oxide, and removing the complex from the mixture. This process has particular utility for removing triphenylphosphine oxide from a mixture--a task that was previously hard to perform.

Triphenylphosphine oxide complex process

A pyridine-2,3-dicarboxylic acid diester of the formula Va ##STR1## where the radicals R.sup.2 and R.sup.4 have the meanings set out in the specification and where R.sup.8 is a C.sub.1 -C.sub.4 -alkyl, C.sub.3 -C.sub.5 -alkenyl or C.sub.3 -C.sub.5 -alkynyl radical, which may be substituted by halogen, phenyl or C.sub.1 -C.sub.4 -alkoxy.

Substituted 3-phenylpyrazoles

A process for preparing polyenecarbonyl compounds having a high all-E content and their acetals or ketals by aldol condensation or Horner-Emmons reaction comprises carrying out the reaction, for the purposes of the preferred formation of a double bond of E configuration and in order to maintain the E configuration of the double bonds in the stating compounds as completely as possible, in the presence of oxygen or an oxygen-inert gas mixture or nitric oxide or a nitric oxide-inert gas mixture and/or in the presence of specific stable radicals and/or in the presence of quinones or quinone derivatives.
