Med Sci (Paris) 2021 Jun-Jul;37(6-7):647-653. Epub 2021 Jun 28.

École des hautes études en sciences sociales (EHESS)/Institut de recherche interdisciplinaire sur les enjeux sociaux (IRIS), Campus Condorcet, Bâtiment Recherche Sud, 5 cours des Humanités, 93322 Aubervilliers, France - Centre de recherche médecine, sciences, santé, santé mentale, société (Cermes3), Chercheure associée.

In France, research on contraception is a dynamic field that has been expanding since the publication of early socio-demographic work in the 1980s. This article offers a synthesis of these publications, by classifying them in four main sociological approaches: a sociology of contraceptive demand (1); a sociology of contraceptive offer, with an attention drawn to the prescription, production, and promotion of contraceptives (2); an institutional approach, focusing on how contraceptive systems are shaped at a national level (3); finally, research on social inequalities in the access to contraceptives (4). The article highlights that the centrality of the pill in the French contraceptive system has been stable for the past 40 years, though oral contraceptives have been the object of growing criticism, particularly in the aftermath of the 2012-13 French pill scare.

Walking metals: catalytic difunctionalization of alkenes at nonclassical sites.

Chem Sci 2020 Sep 7;11(36):9757-9774. Epub 2020 Sep 7.

Department of Chemistry, The Pennsylvania State University University Park Pennsylvania 16802 USA

Migration of metals along a carbon chain is triggered by two of the most common organometallic elementary steps - β-hydride (β-H) elimination and alkene hydrometallation. This process heralds a new future for creating bonds at carbon sites that fall outside the tenets of the conventional wisdom for reactivity and bond formation, and provides an opportunity to leverage β-H elimination to advance the very reaction of alkene difunctionalization it is intrinsically predestined to disrupt. Almost four decades since its genesis, the early adventure for alkene difunctionalization by metal migration was sporadic, and its later development went on a hiatus primarily due to original impetus on arresting β-H elimination for vicinal alkene difunctionalization.
