✦ Synopsis

Several species within genera of the family of red algae Bonnemaisoniaceae have yielded halogenated secondary metabolites. Halogenated heptan-2-ones were isolated from Bonnemaisonia hamifera' and two independent studies of geographically separate collections of Asparagopsis taxiformis 2,3 yielded haloacetones or haloforms respectively as major isolates whilst halobutenones were detected in both studies. We have found haloacetones, including the previously unreported l,l-dibromo-3-iodoacetone, together with bromoform in a freeze-dried sample of A.armata from Australian waters 4 but could detect
