“…In the last few years, we have been contributing in this field and we have demonstrated that solvent‐free conditions (SolFC) have beneficial effects on some organic transformations,7 such as Michael additions,7a,7j oxirane ring‐opening reactions,7e,7f Diels–Alder reactions,7g–7i and [3+2]7c,7d and 1,3‐dipolar7b cycloadditions allowing the chemically and environmentally efficient preparation of target molecules such as 1 H ‐1,2,3‐triazoles, 1 H ‐tetrazoles, biphenyl‐2‐ylcarbonitriles, and benzo[ e ]1,4‐oxathiepin‐5‐ones among others.…”
