Abstract The philicity indices, ω N , and ω S + , characterize a charge transfer process occurring at constant spin number, and the spin polarization for a process at constant number of electrons, respectively. These descriptors are explored for a series of substituted C 2 HSiX silylene isomers (X = F, Cl, Br, H), providing new insights for a comprehensive description of global and local chemical reactivity patterns and halogen substituent effects in these systems.
