A copper-catalyzed alkenetransferhydrodeuteration reaction that selectively incorporates one hydrogen and one deuterium atom across an aryl alkene is described. The transferhydrodeuteration protocol is selective across a variety of internal and terminalalkenes and is also demonstrated on an alkene-containing complex natural product analog. Beyond using 1H, 2H, and 13C NMR analysis to measure reaction

The present invention provides a pyrazole compound of formula (a): ;a noxious arthropod pests controlling composition containing the compound shown by the formula (a) as an active ingredient; and a method for controlling noxious arthropod pests comprising applying an effective amount of the compound shown by the formula (a).
Some (piperidinomethylene)bis(phosphonicacid) derivatives were prepared and their activity to inhibit a rise in serum calcium induced by parathyroid hormone in thyroparathyroidectomised rats was evaluated. Several (4-alkylidene-, 4,4-dialkyl-, or 4-alkyl-4-halopiperidinomethylene)bis(phosphonicacid) derivatives showed considerable inhibitory activity. But compounds having aromatic and polar substituents

commercial catalyst supply. However, the mild instability of TPAP creates preparation, storage, and reaction reproducibility issues, due to unpreventable slow decomposition. In search of attributes conducive to catalyst longevity an extensive range of novelperruthenate salts were prepared. Subsequent evaluation unearthed a set of readily synthesized, bench stable, phosphonium perruthenates (ATP3 and
