Abstract: Compounds according to formula (I) wherein Z is S, SO, or SO2, may be prepared by a process that includes charging to a reactor hydrogen sulfide and an alkyl glycidyl ether according to formula (III), in the presence of a base. The compounds may also be prepared by contacting an alkoxychlorohydrin according to formula (II) with a sulfide source.

Abstract: An attachment assembly for lockably but releasably securing a picture frame or the like to a wall surface. The assembly includes a plurality of bracket plates each having a keyhole opening for coaction with a respective headed fastener element secured to the wall surface, and a locking plate mounted for pivotal movement on one of the bracket plates between an unlocked position in which a mask opening in the locking plate unmasks the head portion of the keyhole opening, to allow passage of the head of the wall fastener element, and a locked position in which the mask opening unmasks the slot portion of the keyhole opening. The mask opening includes a edge surface that extends obliquely across the entrance to the keyhole opening slot portion in the unlocked position of the locking plate and coacts with the shank portion of the wall fastener to rotate the locking plate to its locked position as the shank portion advances into the slot portion of the keyhole opening.
