TL;DR: In this paper, a new method for the stereospecific synthesis of trisubstituted olefin was successfully applied to a highly stereoselective synthesis of 1,5-diene unit.
Abstract: The new method for the stereospecific synthesis of trisubstituted olefin was successfully applied to a highly stereoselective synthesis of 1,5-diene unit, demonstrating the preparation of ethyl geranate [3] starting from 3-methyl-2-butenyl bromide [1].

TL;DR: In this paper, the same authors showed that n-butylmagnesium bromide and cuprous iodide can be obtained in high yield with the perfect retention of configuration.
Abstract: Ethyl (E)-3-methyl-2-heptenoate, 6, or ethyl (Z)-3-methyl-2-heptenoate, 8, was prepared in high yield with the perfect retention of configuration by the reaction of ethyl (E)-3-phenylthio-2-butenoate, 5, or (Z)-3-phenylthio-2-butenoate, 7, with n-butylmagnesium bromide and cuprous iodide, respectively.
TL;DR: In this paper, a synthetisierte Bis-(phenylthio)- cyclopentanon (V) wird in Tetrahydrofuran with Triallylboran (VI) alkyliert; die Abspaltung der beiden Phenylthiogruppen, die mit Quecksilbersalzen nur mit schlechter Ausbeute verlauft, erfolgt with zwei Aquivalenten Silberperchlorat in Benzol unter = ′ Bildung des Cyclopent
