Tertiary 1,5-hexadien-3-ols are transformed at room temperature into δ-ethylenic ketones in 35-90%, yields under two sets of conditions: treatment with one molar equivalent of mercuric trifluoroacetate followed by demercuration of the intermediate α-mercuro ketone with sodium Nike Free Trainers Uk borohydride; and treatment with 0.2 molar equivalent Nike Roshe Trainers of t of lithium trifluoroacetate or trifluorométhansulfonate. The reactions are highly stereoselective, the E isomer of the ketone forming 80-95% of the product. The highest selectivity was observed under the second conditions. The theory of plate tectonics rests essentially Nike Roshe Run Palm Trees on paleomagnetism data and on the results of submarine cores which are evidence of continuous sea-floor spreading. Each oceanic plate is connected to the adjacent continent. Its continuous movement (a few centimeters per Buy Nike Roshe Run Online year) accounts for the hypothesis of “continental drift” put forward by Wegener around the turn of the century and explains the formation of mountain ridges and ocean pits. In connection with the paleogeography of the epicontinental seas, sea-floor spreading allows a better understanding of mammal migrations during the Cenozoic era.
