Over the past 50 years, extensive research has uncovered numerous chemical systems capable of activating C–H bonds, but the fundamental steps leading to C–H bond cleavage remain limited. The established C–H activation mechanisms are insufficient to enable all desired transformations, making the exploration of new reaction pathways important.

Phillip Grant's research focuses on distal C–H bond activation. He proposed a novel method for C–C bond formation via distal proton elimination. He and his colleagues conducted in-depth experimental and computational studies in the reaction system of cyclodecyl carbonium ions, identifying conditions that selectively promote distal elimination reactions. This method not only provides new insights into distal C–H bond activation but has also been effectively validated in the synthesis of decalins, filling a gap in this research area.

In synthetic organic methodology, he and his colleagues developed a new class of olefination reaction: utilizing thiourea-based sulfur ylides with aldehydes or sulfonyl imines, they enabled the selective synthesis of Z- or E-configured olefins. This achievement transcends the traditional limitation of viewing phosphonium and sulfur ylides as two distinctly reactive systems, providing a flexible tool for olefin construction.

These works not only expanded the research boundaries of C–H activation and olefination reactions but also provided a new methodological foundation for the synthesis of complex molecules, demonstrating his innovative approach and systematic thinking in solving cutting-edge problems in organic chemistry.
