Reactions of benzene vapor-calcium atom with organic halides and carbonylcompounds were examined. Benzene vapor-calcium atom reacted with organic halides (RX) to give phenyl-substituted products (PhR) and reduced products (RH). The reactions of benzene vapor-calcium atom with ketones (RR′CO) or benzaldehyde gave two kinds of alcohol PhRR′COH and RR′CHOH, or Ph2CHOH and PhCH2OH, respectively
