The crystal belongs to the orthorhombic system, space group Pbca with α = 18.441（2）, b = 8.3284（9）, c = 19.257（2） A, Z = 8, V = 2957.5（5） A3, Mr = 279.37, Dc = 1.255 mg/m3, S = 1.033, μ =0.219 mm^-1, F（000） = 1184, the final R = 0.0349 and wR = 0.0876 for 2629 observed reflections （I 〉 2σ（I））. X-ray crystal structure presents the intermolecular N–H···N hydrogen bond, which plays an important role in stabilizing the crystal structure. The preliminary bioassay indicates that the title compound exhibits potent fungicidal activity against R. Solani （25 mg/L） with inhibition rate of 80.0%.展开更多
In order to find novel herbicidal active compounds, a series of N-（2,2-dimethyl-7-alkoxy-2,3-dihydro- benzofuran-5-yl）-2-（4-arylxoyphenoxy）propionamides was designed, prepared and evaluated for their herbicidal ac...In order to find novel herbicidal active compounds, a series of N-（2,2-dimethyl-7-alkoxy-2,3-dihydro- benzofuran-5-yl）-2-（4-arylxoyphenoxy）propionamides was designed, prepared and evaluated for their herbicidal activity. Bioassay results showed that most of the title compounds had excellent and selective herbicidal activity against the monocotyledonous grasses. In particular, compounds lg and lm showed 100% inhibition against the growth of three monocotyledonous grasses under both postemergence and preemergence treatments at the dose of 2250 g/hm2 （1 hm2= 104 m2）, and could be used as lead compounds for further development of novel potential herbicidal agents.展开更多
