abstract: a green route to the synthesis of piperonyl acetone
[55418-52-5] is reported. this environmental-pollution free
synthesis of piperonyl acetone involves the hydrogenation of
piperonylene-acetone [4-(1,3-benzedioxole)-3-buten-2-one [3160-37-0]]
from cinnamomum petrophilum leaves oil catalyzed by 5% Pd/C. the
cinnamomum petrophilum leaves oil is an essential oil from leaves of
a plant of cinnamomum petrophilum nees chao. the piperonyl acetone is
a perfume and an intermediate of some medicines. thus, a mixt. of
1908.0g (purity 99.6%) of piperonyleneacetone, 15 g of 5% Pd/C, and
6000 mL of ethanal was stirred for 3.0 h at 120C, under hydrogen
pressure of 1.5MPa to give 1671.5g of piperonyl acetone (purity
98.9%, yield 86.1%). this process can be given 85.8% yield of
piperonyl acetone from piperonal[120-57-0] without any waste and
waste water.
