    摘要: A perfume composition including at least one compound having the formula: wherein p, q and r are independently selected from 0 and 1, p+q+r being from 0-3 and X1 is saturated or unsaturated, such that: (a) when p+q+r=0, R1, R2 and R12 are Me; R3-5 and R9-11 are H; (b) when p+q+r=1, R1 and R12 are independently selected from H, Me and Et; R2 is selected from H and C1-C4 alkyl; R3-5 and R9 are independently selected from H and methyl; and R8 and R10 are H; (c) when p+q+r=2, R1 and R2 are selected from H and C1-C4 alkyl, R3 and R9-12 are independently selected from H and methyl: R4-5 are H, or R4 and R5 together form a methylene group; and R6-7 are H; (d) when p+q+r=3, R1, R2 and R12 are Me; and R3-11 are H.

    摘要: A method of making a 3-alkylcycloalkanol of formula 2: where R1 represents a methyl or ethyl group, R2 represents hydrogen, R3 represents an ethyl, propyl, butyl, isobutyl or isoamyl group, R4 represents hydrogen and R5 represents hydrogen, or a methyl, ethyl, propyl, isobutyl or isoamyl group comprises the following steps: (1) carrying out an electrophilic substitution reaction of an alkyl group or precursor thereof, on an ortho-substituted alkylbenzene compound of formula 3: where R6 represents hydrogen, or a methyl or ethyl group; (2) hydrogenating the reaction product of step (1); (3) performing an elimination reaction on one or more reaction products of step (2) to produce one or more alkene products; and (4) hydrating the one or more alkene products of step (3) to provide a 3-alkylcycloalkanol of formula 2. The electrophilic substitution reaction of step (1) may be a Friedel-Crafts acylation, e.g. using an isopropyl ketone precursor, or a Friedel-Crafts alkylation, e.g. using an isobutyl group. The 3-alkylcycloalkanols, especially 3-(2-methylpropyl)-1-methylcyclohexanol, are useful fragrance materials and find use in perfumes and perfumed products.

    摘要: A clip comprising first, second and third clamping elements which are connected together by a common biasing element. The biasing element comprises a flat plate of stainless steel which is folded to form a spring which biases a part of the first element and a part of the second element together to form a primary clamp. The biasing element also biases a part of the second element and a part of the third element together to form a secondary clamp.
