The R associations CMa R1 and Mon R1 have been searched for compact 7.6-cm sources with the RATAN-600 radio telescope. The Mon R1 region shows only about the expected number of background radio galaxies; in CMa R1 seven sources of small angular size with S of no more than 30 mJy have been found, two of them probably background objects. Comparison with optical data for CMa R1, together with previous RATAN-600 data for Mon R2, yields an initial mass function chi(M) varies as M exp - 2.7 + or - 0.7 for the rather massive (M is equal to about 10 solar mass) stars in these associations. 28 references.
