A two-step sequence for the synthesis of various 3,4-dihydro-2H-1,3-thiazines is presented. In the first step, 2H-1,3-thiazines were prepared by a new multicomponent reaction (MCR). Starting from β-chlorovinyl aldehydes, this MCR offers an efficient and facile access to 2,2-dialkyl- and 2-alkyl-2-aralkyl-5,6-diaryl-2H-1,3-thiazines. The potential of these(More)
2-Phosphanyl-substituted imidazolium salts 2-PR2(4,5-Cl-Im)[OTf] (9a,b[OTf]) (4,5-Cl-Im = 4,5-dichloro-1,3-bis(2,6-di-isopropylphenyl)-imidazolium) (a: R = Cy, b: R = Ph) are prepared from the reaction of R2PCl (R = Cy, Ph) with NHC 8 (4,5-dichloro-1,3-bis(2,6-di-isopropylphenyl)-imidazolin-2-ylidene) in the presence of Me3SiOTf. 5-Phospanyl-substituted(More)
Maritime situation awareness is supported by a combination of satellite, airborne, and terrestrial sensor systems. This paper presents several solutions to process that sensor data into information that supports operator decisions. Examples are vessel detection algorithms based on multispectral image techniques in combination with background subtraction,(More)
