  The solvolysis of 3,3-dimethyl-2-oxo- and 2,2-dimethyl-3-oxo-1-norbornyl triflates (6 and 8) takes place with formation of ring contracted and fragmented products respectively. The effect of the substituents on the solvolysis rates is explained taking into account n- and σ-participation. This n,σ-participation causes changes in the structure and stability of the intermediate carbocations, which can

  The present invention provides a material for forming a protective film that has favorable alkali solubility and gives a protective film excelling in water repellency, as well as a method for forming a photoresist pattern using this material for forming a protective film. The material for forming a protective film of the present invention contains an alkali-soluble polymer having a unit derived from a monomer represented by the following general formula (A-1) as a constitutional unit. In the general formula (A-1), R 1 is a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or the like; R 2 , R 3 , and R 4 are each independently an alkylene chain having 1 to 6 carbon atoms or the like; R 5 and R 6 are each independently an alkyl group or fluoroalkyl group having 1 to 15 carbon atoms or the like; and at least one of R 5 and R 6 is a fluoroalkyl group; Z is an alkylene chain having 1 to 2 carbon atoms or an oxygen atom; m is 0 or 1; and n is an integer of 0 to 3.

  The σ-participation of the C2-C3 and C4-C7 bonds in the solvolysis of methyl substituted 1-norbornyl triflates is evaluated by application of the additivity principle. It is concluded that the σ-participation of the C2-C3 bond is dependent on the spatial orientation of methyl substituents.
