Narrative:
I climbed the beechjet from FL350 to FL390. Airspeed of beechjet was 100 mph slower and appeared that aircraft would pass safely behind the B737 at FL370. I subsequently turned the beechjet 50 degrees to the right. The B737 at FL370 was switched to the next sector. While not actually a contributory factor, the next sector attempted to turn the B737, but was unable to establish radio contact during 3 xmissions. This is a common problem for both our sectors. It is reported to maintenance, but is never solved.
