Joining efficiency

Aldehyde 170 is to serve as the electrophile in an intermolecular Homer-Wadsworth-Emmons (HWE) reaction70 with enantiomeri-cally pure phosphonate 169. Compounds 169 and 170 can in fact be joined efficiently under the mild reaction conditions shown in Scheme 50 to give a,/ -unsaturated imide 206 (96 % yield). The use... [Pg.618]

Spin Welding. Spin welding is an efficient technique for joining circular surfaces of similar materials. The matching surfaces are rotated at high speed relative to each other and then brought into contact. Frictional heat melts the interface and, when motion is stopped, the weld is allowed to soHdify under pressure. [Pg.370]

In the early part of the 1990s deliberations on appliance efficiency standards appeared to be heading toward greater consensus. Manufacturers, efficiency advocates, and states joined together to discuss a negotiated joint proposal for the second DOE revision under NAECA of refrigerator standards, which was to be issued in 1995. All major parties submitted a joint proposal to DOE in late 1994. [Pg.80]
