Grassroots Agency: Participation and Conflict in Buenos Aires Shantytowns seen through the Pilot Plan for Villa 7 (1971–1975)

open access articleIn 1971, after more than a decade of national and municipal policies aimed at the top-down removal of shantytowns, the Buenos Aires City Council approved the Plan Piloto para la Relocalización de Villa 7 (Pilot Plan for the Relocation of Shantytown 7; 1971–1975, referred to as the Pilot Plan hereinafter). This particular plan, which resulted in the construction of the housing complex, Barrio Justo Suárez, endures in the collective memory of Argentines as a landmark project regarding grassroots participation in state housing initiatives addressed at shantytowns. Emerging from a context of a housing shortage for the growing urban poor and intense popular mobilizations during the transition to democracy, the authors of the Pilot Plan sought to empower shantytown residents in novel ways by: 1) maintaining the shantytown’s location as opposed to eradication schemes that relocated the residents elsewhere, 2) formally employing some of the residents for the stage of construction, as opposed to “self-help” housing projects in which the residents contributed with unpaid labor, and 3) including them in the urban and architectural design of the of the new housing. This paper will examine the context in which the Pilot Plan was conceived of as a way of re-assessing the roles of the state, the user, and housing-related professionals, often seen as antagonistic. The paper argues that residents’ fair participation and state intervention in housing schemes are not necessarily incompatible, and can function in specific social and political contexts through multiactor proposals backed by a political will that prioritizes grassroots agency

Stereocontrolled Synthesis Of Enantiomerically Pure Dienyl Sulfoxides Via Palladium-Catalyzed Coupling Reactions

The palladium-catalyzed coupling of enantiopure 2-halovinylsulfoxides and (E)-vinyl stannanes proceeds in an efficient, stereospecific manner to afford enantiopure 1-sulfinyldienes

Synthesis Of Enantiomerically Pure (Z)-2-Haloalkenyl Sulfoxides

Efficient procedures to prepare enantiomerically pure (Z)-2-haloalkenyl sulfoxides from alkynyl sulfoxides are described

Stereocontrolled Synthesis Of Enantiomerically Pure 2-Dienyl Sulfoxides Via Palladium-Catalyzed Coupling Reactions

Enantiopure 2-sulfinyl dienes can be prepared via regio- and stereoselective hydrostannylation of alkynylsulfoxides; after conversion to the corresponding vinyliodides these substrates may be coupled with vinylstannanes via Stille methodology in the presence of BHT

Diastereoselective Formation Of An [Eta(4)-(1z)-Sulfinyl Diene]Iron(0) Tricarbonyl Complex. Diastereoselective Allylation Of The Derived Iron Dienal

An enantiomerically pure (1Z,3E)-sulfinyl diene exhibited a high degree of facial selectivity (alpha:beta = 16:1) upon complexation to an iron(0) tricarbonyl fragment, producing a [eta(4)-(1Z)-sulfinyl diene]iron(0) tricarbonyl complex (2; 80%). The iron(0)-dienal complex derived from 2 can undergo a highly diastereoselective allylation with allyltri-n-butylstannane and BF3 . Et(2)O (diastereomer ratio 95:5); the absolute stereochemistry of the homoallylic alcohol product (4) was established by X-ray crystallography

Synthesis And Diastereoselective Complexation Of Enantiopure Sulfinyl Dienes: The Preparation Of Sulfinyl Iron(0) Dienes

The preparation of a diverse array of enantiomerically pure 1- and 2-sulfinyl dienes has been achieved via Stille coupling of halovinyl sulfoxides and vinyl stannanes, hydrogenation of 1-sulfinyl-1-en-3-ynes, or vinylcupration of 1-sulfinyl alkynes. Formation of the corresponding sulfinyl diene iron(0) tricarbonyl complexes was accomplished by utilizing Fe(CO)(5)/NMO or (bda)Fe(CO)(3) as iron(0) tricarbonyl transfer reagents. Installation of the iron(0) tricarbonyl fragment was shown to be highly diastereoselective (10-16:1) for (R)-(1Z)-1-sulfinyl dienes, most likely as a result of allylic 1,3-strain. The synthesis of a 1-sulfinyl-1,3,8,10-tetraene is also described
