Novel benzamide derivatives, N-[1-(aminocarbonyl)-2-(1-piperidinyl)ethyl]benzamides (4 and 5), were prepared from the reaction of beta-piperidinoalanine (6) as the starting material.

A general visible light induced direct difluoromethylation of N-methacryloyl benzamides by using difluoromethyl sulfone was developed. In addition, photoredox-catalyzed trifluoromethylation of N-methacryloyl benzamides with trifluoromethyl sulfone via a similar radical process was also achieved. This method allows for an efficient and practical synthesis of a variety of CFH/CF-containing isoquinoline-1,3(2H,4H)-diones in moderate to good yields.

Silages were prepared in six laboratory experiments from four direct-cut grassland swards and pure swards of perennial ryegrass and false oat with dry matter contents ranging between 180 and 325 g/kg. Grass was fermented at 22 degrees C and silages were stored at the same temperature for 4 months. Untreated silages (negative control) and silages preserved with 3 g/kg of formic acid (positive control) were compared with silages inoculated with commercial strains of Lactobacillus plantarum, Lactobacillus buchneri and a mixed preparation Microsil.

Silages from five ripened varieties of silage maize with dry matter contents ranging between 275 and 410 g/kg were prepared in five laboratory experiments. Whole-plant maize was fermented at 22 degrees C and silages were then stored at the same temperature for 4 months. Spontaneously fermented silages were prepared as control variants and compared with silages inoculated with commercial strains of Lactobacillus plantarum, Lactobzcillus buchneri and a mixed preparation Microsil containing L.
