We present IRAM 30 m telescope observations of the CO(1–0) and (2–1) lines in a sample of 11 group-dominant elliptical galaxies selected from the CLoGS nearby groups sample. Our observations confirm the presence of molecular gas in 4 of the 11 galaxies at >4σ significance, and combining these with data from the literature we find a detection rate of 43 ± 14%, comparable to the detection rate for nearby radio galaxies, suggesting that group-dominant ellipticals may be more likely to contain molecular gas than
