In this paper, we present a virtual laboratory platform (VLP) baptized Mercury allowing students to make practical work (PW) on different aspects of mobile wireless sensor networks (WSNs). Our choice of WSNs is motivated mainly by the use of real experiments needed in most courses about WSNs. These experiments require an expensive investment and a lot of nodes in the classroom. To illustrate our study, we propose a course related to energy efficient and safe weighted clustering algorithm. This algorithm which is coupled with suitable routing protocols, aims to maintain stable clustering structure, to prevent most routing attacks on sensor networks, to guaranty energy saving in order to extend the lifespan of the network. It also offers a better performance in terms of the number of re-affiliations. The platform presented here aims at showing the feasibility, the flexibility and the reduced cost of such a realization. We demonstrate the performance of the proposed algorithms that contribute to the familiarization of the learners in the field of WSNs.

An efficient synthetic method of Z-selective 3-ethoxycarbonyl-2-halo-1,3-dienes and 3-vinyl-2-halo-1,3-dienes was developed from the reaction of allenols having ethoxycarbonyl and vinyl group with indium trihalides at room temperature in CH₂Cl₂.

<P><B>Abstract</B></P><P>A synthetic method was developed for the preparation of vinyl sulfides and vinylamines from arylalkynyl phenyl sulfides and sulfonamides. Under mild conditions, a catalytic intramolecular hydroarylation reaction was carried out in the presence of FeCl<SUB>3</SUB> and AgOTf (OTf = trifluoromethanesulfonate) in 1,2‐dichloroethane. A variety of 1,2‐dihydronaphthalenes, 2<I>H</I>‐chromenes, and 1,2‐dihydroquinolines containing a phenylsulfenyl or <I>N</I>‐phenyl‐<I>N</I>‐tosyl group on the sp<SUP>2</SUP>‐hybridized benzylic carbon were prepared in good to excellent yields. The present method could be extended to the preparation of dihydropyrano[2,3‐<I>g</I>]chromenes through a twofold Fe‐catalyzed hydroarylation by a selective 6‐<I>endo</I> mode.</P>
