Recent advances in organic synthesis using light-mediated n-heterocyclic carbene catalysis

The combination of photocatalysis with other ground state catalytic systems have attracted much attention recently due to the enormous synthetic potential offered by a dual activation mode. The use of N-heterocyclic carbene (NHC) as organocatalysts emerged as an important synthetic tool. Its ability to harness umpolung reactivity by the formation of the Breslow intermediate has been employed in the synthesis of thousands of biologically important compounds. However, the available coupling partners are relatively restricted, and its combination with other catalytic systems might improve its synthetic versatility. Thus, merging photoredox and N-heterocyclic carbene (NHC) catalysis has emerged recently as a powerful strategy to develop new transformations and give access to a whole new branch of synthetic possibilities. This review compiles the NHC catalyzed methods mediated by light, either in the presence or absence of an external photocatalyst, that have been described so far, and aims to give an accurate overview of the potential of this activation modeL.M. acknowledges the Autonomous Community of Madrid (CAM) for the financial support (PEJD-2019-PRE/AMB-16640 and SI1/PJI/ 2019-00237) and for an “Atracción de Talento Investigador” contract (2017-T2/AMB-5037

POLICY FOR THE'DESERVING,'BUT POLITICALLY WEAK: THE 1996 WELFARE REFORM ACT AND BATTERED WOMEN

The Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (Public Law #104-193) is perhaps the most visible national legislation since the sweeping Civil Rights laws of the 1960s. For social policy so well entrenched into the American social fabric, the rapidity with which reforms swept through the welfare system was unprecedented and confound conventional theoretical pronouncements on bureaucracy and policy change. The swiftness of reform, and the political rhetoric that surrounded the 1996 Welfare Reform Act, have prompted criticism that reformers responded more to the social construction of welfare recipients than they did to the dictates of sound public policy (Magusson and Dunham, 1996). This article discusses the ramifications of the 1996 Welfare Reform Act for battered women and concludes that battered women's social construction as deserving of public assistance, but politically weak, precipitated welfare reform policy, targeted to battered women, that has been largely rhetorical rather than substantive.
