Can explosions work in space?

Wouldn't claymore mines, which blast the area in front of them with BBs, and other scatter shot type weapons still be rather effective since they're using high velocity solid matter to do the damage rather than pressure waves? I suppose they'd either need to be in sunlight if in the inner solar system or have a heat source otherwise  to ensure the reaction required for the chemical explosive is still spontaneous. Maybe if grenades or other devices were designed with spikes of tungsten or something, it could maximize the shrapnel damage.
