    摘要： Saturated and/or unsaturated monohydric alcohols are added to allylic halides in the presence of copper (I) halide and a solid organic-insoluble acid acceptor such as MgO to form ethers in which at least one and preferably both of the organic groups attached to the ether oxygen atom contains a single carbon-to-carbon double bond.

    摘要： A lock nut assembly comprises a sleeve bolt (1), a clamp bolt (6) and a locking bolt (7). The sleeve bolt (1) has a hollow shank with an internally threaded portion (5) at one end and a head (3) having an axial bore (2) extending through it at the other end, at which it is internally threaded (4). The clamp bolt (6) also has a hollow shank with an externally threaded central portion (9) and an internally threaded portion (10) at one end (10) and a head (8) at its opposite end. The locking bolt (7) has an externally threaded portion at one end (12) and a head (11) at its opposite end. The central portion (9) of the clamp bolt (6) and the internally threaded portion (5) of the sleeve bolt (1) are dimensioned for co-operation with threads of one hand, and the second portion (10) of the clamp bolt (6) and the externally threaded portion (12) of the locking bolt (7) are dimensioned for co-operation with threads of opposite hand. In use, the clamp bolt (6) is screwed into the sleeve bolt (1), the locking bolt (7) is screwed into the clamp bolt (6) via the hollow shank of the sleeve bolt (1) and, because of the opposite handedness of the respective co-operating threads, the assembly will resist any tendency to undo. Further, components between the heads (3, 11) of the sleeve bolt (1) and clamp bolt (7) will be retained there with a substantially constant predetermined torque.
