With ethylene derivs

Reaction of an amino group, present in a side chain of 7-oxo-lH,3H,7H-pyrido[3,2,1-z/J[3,1 Jbenzoxazine-6-carboxyhc acids, with ethylene derivatives in the presence of a base in DMSO yielded (2-substituted ethyl)amino derivatives (06WOP2006/050940, 06WOP6006/050943). [Pg.23]

These molecules (isoelectronic with ethylene derivatives) are planar and have short B-N bonds. Borazine B3N3H6 is isoelectronic with benzene and has a similar planar, hexagonal structure. It is probably best formulated as ... [Pg.195]

At room temperature, water also induces formation of 1,3-dipoles which undergoes a quantitative [3 + 2]cycloaddition reaction with maleimide. Cycloaddition with ethylenic derivatives requires the additional use of acetic acid.400... [Pg.310]

In studies of a number of acylsilanes the carbonyl carbon was found to be deshielded by 30 ppm compared to the carbon analogues with chemical shifts ranging from 188-246 ppm31. The 13C chemical shifts for several of these compounds are collected in Table 5. In the same paper Brook and coworkers reported the chemical shifts for some silaethylenes (one of which had been reported earlier32) which also experienced substantial deshielding (> 40 ppm) compared with ethylene derivatives of similar substitution. Values for these compounds are shown in Table 6. [Pg.519]

Yet, it should be stated that sucrose will not be competing with ethylene it will be competing with ethylene derivatives which, in fact, cost more than ethylene by factors of two or three. [Pg.366]

In contrast, cationic addition is only efficient with ethylene derivatives that contain an electron-donating group, such as the following examples. [Pg.1274]
