This progress report fits in a large study of the binary population in the Sco--Cen Complex (Lower Centaurus Crux (LCC), Upper Centaurus Lupus (UCL) and Upper Scorpius (US)). With the identification of astrometric members of these associations based on the Hipparcos satellite data, statistics predict some 90, mostly fainter, spectroscopic binaries to await detection. A first--look analysis of two recent high--resolution spectroscopic runs on 53 stars reveals 5 SB2s (one doubtful), including two newly detected ones.
