Hydrogenation reaction under low H2 pressure atmosphere is of great interest from a safety view point because H2 gas is highly flammable in air and shows explosion triggered by spark, heat or sunlight. In this work, Rh complex catalyst- MOF hybrid was newly synthesized and used as catalyst for hydrogenation of alkene substrates. Thanks to the activation of Rh complex catalyst during the immobilization process and intrinsic gas condensation property of MOF, the resulting composite showed much higher catalytic activity than the complex catalyst itself. Noteworthy, the composite can maintain its catalytic activity even under low H2 pressure that cannot support the reaction with the complex catalyst alone. Furthermore, in contrast to the complex catalyst, the composite maintained its catalytic activity even without solvent, providing environmentally friendly approach to catalysis.
