title: Pentamethylcyclopentadienyl rhodium(III) trifluorovinyl phosphine complexes and attempted intramolecular dehydrofluorinative coupling of pentamethylcyclopentadienyl and trifluorovinyl phosphine ligands

authors: Barnes, Nicholas

subjects: Trifluorovinylphosphines

abstract: The trifluorovinyl phosphine complexes [Cp*RhCl₂{PR3−x(CF CF₂)x}] (1 x = 1, a R = Ph, b Pri, c Et; 2 x = 2, R = Ph) have been prepared by treatment of [Cp*RhCl(μ-Cl)]₂ with the relevant phosphine. The salt [Cp*RhCl(CNBut){PPh₂(CF CF₂)}]BF₄, 3, was prepared by addition of ButNC to 1a in the presence of NaBF₄. The salt [Cp*RhCl{κP,κS-(CF₂ CF)PPh(C₆H₄SMe-2)}]BF₄ was prepared as a mixture of cis (5a) and trans (5b) isomers by treatment of [Cp*RhCl(μ-Cl)]₂ with the phosphine-thioether (CF₂ CF)PPh(C₆H₄SMe-2), 4, in the presence of NaBF₄. The structures of 1a–c and 5a have been determined by single-crystal X-ray diffraction. Intramolecular dehydrofluorinative carbon–carbon coupling between pentamethylcyclopentadienyl and trifluorovinylphosphine ligands of 1a, 3 and 5 has been attempted. No reaction was observed on treatment of the neutral complex [Cp*RhCl₂{PPh₂(CF CF₂)}], 1a, with proton sponge, however, 5a underwent dehydrofluorinative coupling to yield [{η⁵,κP,κS-(C₅Me₄CH₂CF CF)PPh(C₆H₄SMe-2)}RhCl]BF₄, 6. Other reactions, in particular addition of HF across the vinyl bonds of 5, occurred leading to a mixture of products. The cation of 3 underwent similar reactions.

title: Mindful publishing in the AI era: Navigating trends and fostering environmental awareness

authors: Medvedev, Oleg N.

abstract: Mindful publishing plays a key role in bridging technological advancement with environmental mindfulness. This presentation is offering an editor’s perspective on the current trends and future directions in the publishing world, with a central focus on fostering environmental awareness by considering potential benefits and risks of AI engagement.
Drawing upon recent data and publications journals such as Mindfulness, we illustrate the powerful potential for a symbiotic relationship between mindfulness research, AI technologies and environmental stewardship in publishing. The talk further navigates the emergent pathways of conducting research and dissemination of knowledge leveraging AI tools, while minimizing environmental footprint. 
By introducing the Special Issue on Environmental Mindfulness, we invite stakeholders to explore the landscape of mindful publishing in the AI epoch, a venture promising to open fresh avenues for research and discussions. By delineating the contemporary nexus of mindful publishing and AI, we aim to spearhead a movement towards more conscious, environmentally sustainable knowledge dissemination paradigms, thereby championing the nurturing of a society that is both informed and sustainable.

title: Te Mauri o te Kaitiaki - Exploring Te Ao Māori in environmental relations and kaitiakitanga  in Aotearoa New Zealand

authors: Wareka, Mona-Lisa

subjects: Te Ao Māori

abstract: Indigenous environmental empowerment is on the rise as humans look at ways to slow the adverse effects of anthropogenic environmental degradation. In the context of Aotearoa New Zealand, the concept and practice of ‘kaitiaki’ and ‘kaitiakitanga’, respectfully, play a significant role in the co-existence of Māori with the natural world. Previous research shows the innate connections and responsibilities encompassed in being kaitiaki which extend beyond the human element to encompass nonhumans and spiritual manifestations. This research aims to illustrate how Māori use cultural values, concepts and practices in local-level conservational practices through ethnographic research in Matapōuri. I investigate the conflicts and convergences of a rāhui recently placed on two cultural significant areas to the local hapū, and through this, I analyse the practical and spiritual application of kaitiakitanga. Based on this ethnography, I discuss a model for relating environmental degradation with the wellbeing of Māori within Aotearoa New Zealand today. Here, I wish to highlight the ecological and cultural threats present from continuing in the current system. Lastly, I argue that the assertion of kaitiakitanga at the local-level is also an assertion of Indigenous autonomy for Māori and the environment.
