The reactivities of 1-methyl-, 1-ethyl-, and 1-isopropylpyrazoles follow the inductive order of the alkyl group. The rate of iodination of the pyrazole neutral molecule was estimated from those of the 1-alkyl derivatives and the relative rate kP lkP for the uncatalyzed reaction was estimated to be in the range 3 x 109 to 7 x 1012, or even larger if it is assumed that the anionic substrate undergoes attack by molecular iodine (the probability of encounter between the anion and IOH2+ is very small) and the neutral substrate by either I, or IOHo+. 

Recently transalkylation of pyrazoles was demonstrated by Grandberg and Kost.626 On heating with benzyl chloride in an open vessel at 150°, 1-methyl-, 1-ethyl-, and l-propyl-3,5-dimethyl-pyrazole replaced the 1-alkyl by a benzyl group. Both decompositions... 

The photochromic response of spirooxazines was shown to be somewhat affected by the substituent on the indolino nitrogen5 (Table 2.2). For various 1-alkyl-5,6-dimethyl-9 -methoxy NISOs in cellulose acetobutyrate, photochromic activity increased in the order 1-methyl < 1-ethyl < 1- n-propyl < l- -butyl. However, the effect was not straightforward. 

Itoh and Nagakura reported two overlapping 395 nm i mds for 1-methyl-, 1-ethyl- and l-isopropyl-4-carbomethoxypyridinyl radicals, in isopentane solution and 77 K matrices, an observation confirmed for MTHF solutions and thin films...
