This is due to additional ring strain introduced into the smaller ring by sp 2 centers. 40) No 41) Triethylamine. Amines can serve as both nucleophiles and as bases in reactions with alkyl halides. Increasing the steric bulk about the nitrogen diminishes the nucleophilicity while allowing the amine to continue to function effectively as a base. 42) cyclopentene 43) 44) 45) Zn/CH 3 CO 2 H 46) No 47) (Z)-5-chloropent-2-ene 48) 49) Fini...
