Compound, resist composition and method for producing resist pattern

A compound represented by formula (I1):

• wherein, in formula (I1),
• R1 represents a hydrocarbon group having 3 to 36 carbon atoms which has a substituent, and the hydrocarbon group includes an alicyclic hydrocarbon group, and the substituent is selected from the group consisting of a halogen atom, a cyano group, a hydroxy group, a carboxy group, an alkoxy group having 1 to 12 carbon atoms, an alkoxycarbonyl group having 2 to 13 carbon atoms, an alkylcarbonyl group having 2 to 13 carbon atoms or an alkylcarbonyloxy group having 2 to 13 carbon atoms,
• X1 represents *—CO—O—, *—O—CO— or *—O—CO—O, and * represents a bonding site to R1,
• L1 represents a single bond or a hydrocarbon group having 1 to 36 carbon atoms which may have a substituent, and —CH2— included in the hydrocarbon group may be replaced by —O—, —S—, —CO— or —SO2—,
• R2 represents a saturated hydrocarbon group having 1 to 12 carbon atoms,
• u1 represents an integer of 0 to 2,
• s1 represents 1 or 2,
• t1 represents 0 or 1, in which s1+t1 is 2,
• n represents an integer of 2 or more, and
• a plurality of X1, L1, s1, t1, R2 and u1 each may be the same or different from each other.

A resist composition comprising a resin including a structural unit having an acid-labile group, an acid generator and a compound represented by formula (I):

• wherein, in formula (I),
• R1 represents a hydrocarbon group having 4 to 36 carbon atoms which has a substituent, and the hydrocarbon group includes a polycyclic alicyclic hydrocarbon group, and the substituent is selected from the group consisting of a halogen atom, a cyano group, a hydroxy group, a carboxy group, an alkoxy group having 1 to 12 carbon atoms, an alkoxycarbonyl group having 2 to 13 carbon atoms, an alkylcarbonyl group having 2 to 13 carbon atoms or an alkylcarbonyloxy group having 2 to 13 carbon atoms,
