TL;DR: The utilization of CO(2) as a building block may represent an interesting approach to synthetic methodologies less intensive in carbon and energy.
Abstract: The need to reduce the accumulation of CO2 into the atmosphere requires new technologies able to reduce the CO2 emission. The utilization of CO2 as a building block may represent an interesting approach to synthetic methodologies less intensive in carbon and energy. In this paper the general properties of carbon dioxide and its interaction with metal centres is first considered. The potential of carbon dioxide as a raw material in the synthesis of chemicals such as carboxylates, carbonates, carbamates is then discussed. The utilization of CO2 as source of carbon for the synthesis of fuels or other C1 molecules such as formic acid and methanol is also described and the conditions for its implementation are outlined. A comparison of chemical and biotechnological conversion routes of CO2 is made and the barriers to their exploitation are highlighted.

TL;DR: Solid catalysts provide numerous opportunities for recovering and recycling catalysts from reaction environments, which can lead to improved processing steps, better process economics, and environmentally friendly industrial manufacturing.
Abstract: Solid catalysts provide numerous opportunities for
recovering and recycling catalysts from reaction
environments. These features can lead to improved
processing steps, better process economics, and environmentally
friendly industrial manufacturing.
Thus, the motivating factors for creating recoverable
catalysts are large.

TL;DR: This Account highlights recent developments in the Biginelli reaction in areas such as solid-phase synthesis, combinatorial chemistry, and natural product synthesis.
Abstract: In 1893, P. Biginelli reported the synthesis of functionalized 3, 4-dihydropyrimidin-2(1H)-ones (DHPMs) via three-component condensation reaction of an aromatic aldehyde, urea, and ethyl acetoacetate. In the past decade, this long-neglected multicomponent reaction has experienced a remarkable revival, mainly due to the interesting pharmacological properties associated with this dihydropyrimidine scaffold. In this Account, we highlight recent developments in the Biginelli reaction in areas such as solid-phase synthesis, combinatorial chemistry, and natural product synthesis.
