Sommario/riassunto

"Drawing has been growing in recognition and stature within contemporary fine art since the mid-1970s. Simultaneously, feminist activism has been widespread, leading to the increased prominence of women in the art world and the acknowledgement of the crucial role played by gender and sexual difference in constituting the subject. This book argues that these developments did not occur in parallel by coincidence. It uses three works from the 1970s, by Annette Messager, Dorothea Rockburne and Carolee Schneeman, to exemplify critical developments in feminist art history and key moments for drawing as a means of expression. These works are further explored in relation to the contemporary drawing practices of Marco Maggi, Sian Bowen, Susan Hauptmann, Cornelia Parker, Christoph Fink and Toba Kheedori. Dividing its analysis into the themes Approaching, Tropes and Coinciding, the book analyses how both drawing and feminist discourse emphasise dialogue, matter and openness. It demonstrates how sexual



difference, subjectivity and drawing are connected at an elemental level--and thus how drawing has played a vital role in the articulation of the material and conceptual dynamics of feminism.--"

Sommario/riassunto

This book addresses novel C(sp3)-C(sp2) and C(sp3)-heteroatom bond-forming reactions. Two strategies are given in the book using photoredox or electrochemical methods. The first strategy describes that the hydroalkylation of alkynes via photoredox-mediated Ni/Ir dual catalysis produces trisubstituted alkenes as versatile synthetic building blocks for the synthesis of pharmaceutical agents and natural products. High regioselectivity and E/Z-selectivity were achieved by introducing silyl groups that can provide steric and electronic effects to these selectivities with extensive opportunities for post-functionalization. The second strategy enables the development of C(sp3)-heteroatom bond-forming reactions through the electrochemical activation of C(sp3)-B bonds. The bonding of heteroatoms to carbon atoms has been an enduring subject of investigation for organic chemists. The function of most molecules is mainly determined by heteroatoms attached to the carbon atom, although the backbone structure of organic compounds comprises carbon fragments.
