Chiral concepts in s-block metal chemistry
Given the nature of the work undertaken in this project, this thesis will be divided into six chapters. The topics discussed within this thesis primarily focus on the study of chiral bimetallic complexes both from a synthetic and a structural approach. The chemistry of magnesiate complexes will be …

Exploiting cooperative effects in s-Block organometallics for new applications in synthesis and catalysis
… Similarly,advancing in the concept of s-block cooperative bimetallic catalysis, alkali-metal magnesiate complexes [MMg(CH2SiMe3)3] and [(donor)2M2Mg(CH2SiMe3)4] (M = Li,Na or K) have shown that they can also act as catalysts for these hydroamination processes, although longer times and …

Hydro/Solvothermal Synthesis, Structures and Properties of Metal-Organic Frameworks Based on S-Block Metals
… porous MOFs can be synthesized. The use of s-block metals such as calcium, magnesium and rubidium in porous materials is appealing because their ionic binding characters with organic ligands will general flexible MOFs. The bonding interaction of s-block metal centers with carboxylate oxygen …

Synthesis and Coordination Chemistry of Functionalised Phosphazanes
… and their use as ligands and building blocks for macrocyclic compounds. The introduction (Chapter 1) surveys previous literature in the area, which is pertinent to the new studies. One of the most important issues is the various ways in which dimeric phosph(III)azanes can be employed as …

Glide path preparation of nine instrument Systems and their effect on final canal area in simulated canals
… were measured for deviation in both curves. All Blocks were instrumented with K3XF to a final apical size of 35/0.04. Surface areas of preinstrumentation and postinstrumentation images were measured to obtain a percent change for each block and the mean percent change was compared amount groups. …

s-, p-, and f-block metals-mediated novel iron-based compounds as precatalysts for efficient alkaline OER
… that incorporate carefully chosen s-, p-, and f-block metals (spfMs) could effectively address the challenges mentioned above. spfMs typically exhibit two distinct behaviors during alkaline OER: ⅰ) dissolving into the aqueous electrolyte and ⅱ) remaining at the anode as new, insoluble, oxidized …
