L-chloro-2-bromopropane

For example, fragmentation of M+ of l-chloro-3-bromopropane (Fig. 5.15) leads to two alternative fragment ions Hal(CH2)3+. The IE of the corresponding radicals... 

The acetamido alkenethiolate (416), generated by the reductive cleavage of 2,3-dihydro-l,4-thiazin-2-one (415) in liquid ammonia (cf. p. 625), reacted with l-chloro-3-bromopropane in a two-stage process to give (417).

A series of benzimidazole and benzimidazolone derivatives from the Janssen laboratories has provided an unusually large number of biologically active compounds, particularly in the area of the central nervous system. Reaction of imidazolone itself with isopropenyl acetate leads to the singly protected imidazolone derivative 51. Alkylation of this with 3-chloro-l-bromopropane affords the functionalized derivative Use of this...
