In our method, the car image first is divided into a set of 5??5 non-overlapping block and a local direction is defined for each block. The M??N car image is converted to a direction image...
The catalytic addition reactions of ferrocenyl ketones with terminal olefins in the presence of Ru(H) 2 (CO)(PPh 3 ) 3 as catalyst have been studied. Benzoylferrocene reacts with triethoxyvinylsilane, styrene and vinylferrocene, respectively, to give 1:1 coupling products I-III in high yields. C H bond cleavage takes place at the carbon atom of the benzene ring at the ortho...
