Hiyama coupling
  Xiyama birikmasi - bu uglerod-uglerod bog'larini (C-C aloqalari) hosil qilish uchun organik kimyoda ishlatiladigan organosilanlarning organik galoidlar bilan palladiy katalizli o'zaro bog'lanish reaksiyasi. Ushbu reaksiya 1988-yilda Tamejiro Xiyama va Yasuo Xatanaka tomonidan kimyoviy va regioselektivlik bilan sintetik ravishda uglerod-uglerod aloqalarini shakllantirish usuli sifatida kashf etilgan. Xiyama birlashmasi turli xil tabiiy mahsulotlarni sintez qilish uchun qo'llanilgan. R − SiR 3 ″ + R ′ − X → Pd cat.
